AMD Radeon RX 6800 vs RX 6800 XT: Reveiw (2021) Hashrate | Benchemark | Overclocking Settings| Specs | Test | Config Profitability: What will be the mining on AMD Radeon RX 6800 and RX 6800 XT- Most recently, we talked about the new "mining queen" from Nvidia, a video card GeForce RTX 3080... Doctor Lisa Su and the company decided to keep up with competitors and at the end of October an event took place, which was eagerly awaited in the camp of "red" miners. AMD made a presentation of the RDNA 2 line of graphics adapters: Radeon RX 6800, RX 6800 XT. AMD Radeon RX 6800 vs RX 6800 XT Innovative team solution AdvancedMicroDevices was appreciated by computer technology enthusiasts. The red cards of the latest series in games showed higher performance than the RTX 30 based on the Ampere architecture and at the same time they will be sold at a lower price. For a long seven years, flagship green graphics cards dominated the market, but now AMD has managed to get ahead. Optimists believed that there was no need to rush to build mining farms based on the RTX 3080 or RX 5700 XT. It is quite possible that the cards of the new line will become a more profitable option.

By and large, the new version of Navi is an alternative to the 5700 or RTX 3070... But let's talk about everything in order and start with the appearance, new, already on sale AMD video cards. People Also Asked: Common Question RX 6800 vs RX 6800 XT Packaging and appearance of AMD Radeon RX 6800 There have been no dramatic changes in the packaging design and appearance of the next generation AMD graphics adapters. The AMD Radeon ™ RX 6800 graphics card is an almost 30 cm long triple GPU device that occupies 2 slots (while the 6800 XT is 2.5 in total). I must say that parallel to the increase in power, the sizes of video cards are also growing. Compared to the diminutive graphics cards of the early 2000s, today's gaming GPUs look like mastodons that won't fit into a standard case soon. However, for miners this is absolutely unimportant, the main thing is that the cooling system is as efficient as possible and always cope with the loads. But let's see what this miracle of technology can do.

On the thematic forums, they asked many questions like: "Is it really possible to get 150 Mh / s on the 6000 series from AMD on Ethash?" Judging by the "naked" teraflops, the computing power of the green flagship is much higher, while the RTX 3080 produces a maximum of 103 Mh / s. And so it happened. Theoretically, the RX 6800 could not overclock to 100 megahash, even considering the higher core and memory frequencies. If in mining everything depended on the ability of the graphics adapter to work stably at high frequencies, then the more stable overclocking cards with Samsung memory would be worth their weight in gold for miners. Yes, hashrate depends on memory and kernel overclocking parameters, but not to such an extent. Of course, you need to take into account that the new architecture significantly improves performance, and after all, mining, after all, is a banal search of cryptographic codes in search of a suitable option. But you can't argue with the facts, when the new cards were put on the mining of cryptocurrency, they showed what they really could show and nothing more. The forecast based on technical characteristics disappointed those who really hoped for 150 Mh / s, and bench tests confirmed it. Real hashrate table for RX 6800 and RX 6800 XT.

It turns out that on Ether they hardly surpassed their predecessors. However, it should be borne in mind that 5700 XT cards have already learned how to reflash, but no one has tried to modify the BIOS of the RX 6800 yet. Perhaps, over time, folk craftsmen will get to them. Theoretically, with the right timing, these video cards can be overclocked on Ethash up to 70, or even before 75 megahash, but no more. That is, from their competitors RTX 3080, the red video adapters of this series are still lagging behind. Nothing more serious than Radeon VII, the company under the leadership of Dr. Lisa Su never released Overclocking AMD Radeon RX 6800 Overclocking-AMD-Radeon-RX-6800. What can be said about the overclocking of new video cards. You need to set almost the same parameters as on the old 570/580, memory for 2100/2150 and core 1200/1250. These graphics adapters work stably on crypto mining in Windows, but with HiveOS according to the miners' reviews, there are still problems. Devices are detected and started, but failures frequently occur. So, if you buy this model, forget about Hive and bet ten. But with the Nicehash miner, AMD cards of the 60th line are quite compatible. How to reduce the power consumption of video cards The easiest way to reduce card consumption is to lower the Powerlimit. And you can also carry out undervolting, that is, lower the voltage of the graphics core by modifying the BIOS or setting the necessary parameters using specialized software. How-to-reduce-the-power-consumption-of-video-cards The first tests showed that a high Power limit gives nothing but an increase in power consumption. The power limit does not need to be raised much, the maximum +20 is not higher. Reduce voltage using the –cdvc –mcdvc options in the latest version Phoneixminer does not exceed. We need to wait for the developers to release a new release. Now the card consumes about 250 watts. Profitability, purchase relevance At the time of this review, the most profitable algorithm is Ethash. More precisely, the coin is a big Ether, since all other tokens of this algorithm, including Ether classic, are in the second ten of the rating of profitable crypto coins. Profitability, purchase relevance At a speed of 64 megahash video card RX 6800 XT will earn 0.0023 ETH per day, which as of April 24, 2021 is equal to 420 Russian rubles. From this amount, you still need to deduct electricity costs, according to your local tariff. Let's say the net income is 370 rubles per day or 11100 per month. At a price of 115,000 rubles, the card will pay off in 11/12 months. The term is quite acceptable, however, it can radically change both in one and the other direction. What conclusion can be drawn. While the market is in an uptrend, the RX 6800, despite the rather high cost, is very profitable. In purely technical terms, progress is evident, but nothing surprising, AMD could not offer it. Analogs from competitors and cards of previous series for miners are no worse. However, the potential of the new Navi GPU devices has not yet been fully revealed. AMD RX 6800 XT: Review, test (in games) and mining AMD RX 6800 XT Review, test (in games) and mining In this review, we will take a look at the 16 GB version of the AMD RX 6800 XT Reference video card. The card is equipped with 2x8 Pin connectors and consumes from 170 watts to 300 watts depending on overclocking, miner and algorithm.

AMD is positioning the RX 6800 XT as the main competitor to the Nvidia RTX 3080 Average price of RX 6800 XT in Europe is ~ $ 649 ( NOT in Russia!). It turns out that the card will not sell much cheaper than its competitor, the RTX 3080 ($ 700). The RX 6800 XT is still TSMC's 7nm process, just like the RX 5000 series, the Navi 21 has a much larger 519mm² GPU. The RX 6800 XT contains 72 Compute Units (CU) with 64 stream processors for a total of 4608 shaders. The clock speed of the RX 6000 series graphics cards has increased significantly: Game Clock - 2015 MHzBoost Clock - 2250 MHz For comparison: Game Clock RX 5700 XT - 1755 MHz. AMD has also increased the memory capacity by installing 16GB of GDDR6 memory in each RX 6000 model (however, lower-end models are likely to get less memory). The memory is clocked at 16 Gbps and operates over a 256-bit memory interface with a total bandwidth of 512 GB / s. AMD has also implemented 128MB Infinity Cache on the Navi 21 GPU to dramatically increase effective memory bandwidth without excessive power consumption. In terms of power consumption, the RX 6800 XT has a rated total power (TBP) of 300W , which is 75W more than the RX 5700 XT. Equipment The AMD RX 6800 XT comes in a black box with the graphics card on the front and the "AMD" logo. The back of the package is almost completely blank except for a couple of labels. Inside, the card is packed as follows: Cooling system As we wrote earlier (in our review on the Rx 6800), AMD completely redesigned the cards in the new 6000 lineup! The casing of the card is made of aluminum with some protruding silver accents that add contrast to the black metal. It is certainly very important that AMD finally ditched the turbine -style design that it has been using for years. Now we have a card with 3 massive coolers (which we are used to seeing from vendors such as Asus, MSI, etc.) - 90 millimeters each . Air from the fans is pushed out of the side of the card. The main design difference between the RX 6800 and the RX 6800 XT is thickness. Both cards are the same size, but the 6800 XT is 2.5 slots thick and the 6800 is the standard design that takes up 2 slots! On the front side of the card there is a Radeon logo, which, when turned on, lights up with red LEDs - an RGB zone. This is another visual difference between the 6800 and 6800 XT - both RGB zones glow with red LEDs, but the logo lettering itself is silver on the 6800 XT and red on the 6800. The map itself is quite large. Its dimensions are 27 cm x 12 cm. Note that unlike Nvidia ( 3080 and 3090 ), AMD does not use the new power pins. The card has two standard 8-pin PCIe power connectors on the top edge of the card. AMD "Navi 21" uses an external USB 3.2 controller for the USB-C port supplied by Cypress Semiconductor under the number " CYPD5137-40LQXI ". This controller provides USB 3.2 Gen 2 data transfer at 10 Gbps. AMD Radeon RX 6000 series does not support SLI mode! As for the rear panel - the backplate, this model has it! It is almost entirely silver, which increases the length of the card. The backplate is made of metal and protects the card from damage during installation and use. Internal cooling system The copper plate is in contact with the GPU and memory, and the auxiliary aluminum plate conducts heat away from the VRM. Both fins are in contact with an aluminum heatsink, which is blown by three 90mm coolers . The card supports the function of stopping coolers when idle or at low power consumption. Detaching the radiator grill reveals a clean PCB. AMD uses a 12-phase VRM GPU that is powered by the expensive 16-phase Infineon XDPE132G5D VRM controller. The GPU voltage is set to a 12-phase VRM configuration. AMD uses DrMOS International Rectifier TDA21472 components on the Radeon RX 6800 XT, while the RX 6800 uses chips from Alpha & Omega Semiconductor. The memory voltage uses a three-phase circuit controlled by the International Rectifier IR35217 controller. The GDDR6 chips are manufactured by Samsung under the reference number " K4ZAF325BM-HC16 " and are designed to operate at 16 Gbps. Built on the same TSMC N7 (7 nm) as Navi 10, the Navi 21 GPU occupies a 519.8 mm² die area and contains 26.8 billion transistors. The pinkish red tint that we saw on Navi 10 has disappeared. Thermal images All thermal images were taken under maximum load for a general idea and understanding of the cooling system with a slight overclocked core and memory. By installing a thermal camera on top, we get the following indicators: The GPU temperature is kept at around 69 degrees - this is not a very good indicator! Memory at ~ 59 degrees. Unfortunately, unlike the RX 6800 , the RX 6800XT performs much worse in terms of the cooling system. Having installed the thermal camera on the side (from the cooler side), we get the following indicators: The GPU temperature is kept at ~ 69 degrees. Overall, the card looks very cold! Tests in MSI Afterburner show + - the same results, the GPU temperature is at around 71 (73) degrees: Unfortunately, AMD did not make a perfect cooling system for such a powerful card. Yes, 73 degrees is not fatal to the GPU, but not ideal either. Mining test AMD 6800 XT AMD 6800 XT is capable of delivering 59 Mh / s on the Ethash algorithm in stock, while consuming - 235 Watts! With a slight overclocking, the card based on the Ethash algorithm produces ~ 66 Mh / s, with a consumption of 230 watts. How much can you earn Knowing that this video card works well on the Ethash algorithm (Coin Ether ) and knowing its hash rate, you can calculate the payback of this video card, how much it will bring per day, month, year .https://cryptorival.com/widget/calcs/ethereum?calcButtonColorf93&backButtonColorf93&dailyColor4e9f15&weeklyColor09c&monthlyColorf0ad4e&yearlyColord9534f&backColorf5f5f5&addonColoreee...

The card is equipped with 2x8 Pin power connectors. For a farm with 6 AMD 6800 XT video cards and a connected power system (motherboard, SSD, processor), you will need 2 power supplies of 1000 watts each! Outputs The I / O for the AMD 6800 XT graphics card is as follows: 2x DisplayPort 1.41x HDMI 2.11x USB type-C Note that most of the I / O bracket is not vented. Output AMD 6800 XT Reference is not a bad card, with an excellent build and average cooling system. AMD has really gone a long way in the design and power of the card. Despite the fact that the RX 6800 copes well with loads, the same cannot be said about the older brother XT. The Bytwork team recommends AMD 6800 XT reference for purchase. However, if + - at the same price you find cards from vendors, then we advise you to consider them at the beginning, since they are most likely to be better suited to the cooling system for a card of the XT version.Hashrate :66 Mh / s EthashConsumption :300GPU temperature :74 °BPM temperature :68 °Memory temperature :59 ° AMD Radeon RX 6800 XT video card: hashrate - performance in mining other cryptocurrencies AMD Sapphire RX 6800 XT is a representative of AMD's RX 6000 family of video cards, which belongs to the category of professional devices of this series. In terms of performance and cost, it is second only to the flagship RX 6900 XT. The manufacturer announced the price of the new item was $ 649. The RX 6800 XT was launched on November 18, 2020. However, due to insufficient production volumes, the video card was sold out on the same day, which led to a noticeable shortage of the model. With this in mind, the device was sold on some trading platforms with a mark-up of up to 100 percent. The miners are especially interested in how many megahashes 6800 XT gives out on the air, since this is one of the fairly profitable cryptocurrencies for mining at the moment. In the article, we will consider the parameters and characteristics of the card, what is the hashrate of the 6800XT in mining, namely how many hashes it produces on the air and what is the card's performance on other algorithms. AMD RX 6800 XT 16gb: hashrate and main characteristics of the card in mining What is the difference between 6800XT, how many megahashes does it give out? For this, it is worth taking a closer look at the characteristics of the card. The video card has 72 computing units, GDDR6 memory up to 16 GB and a maximum frequency of 2250 MHz. According to users, the performance of the RX 6800 XT outperforms the Nvidia GeForce RTX 3070 by an average of 10 percent. All this is enough for mining cryptocurrencies on any suitable algorithms. Like other top AMD GPUs, the RX 6800 XT delivers top-of-the-line mining performance for Ethereum, Ravencoin and Beam. These cryptocurrencies bring the maximum profit at current rates. The card is equipped with 2x8 Pin connectors and consumes from 170 watts to 300 watts depending on overclocking, miner and algorithm. Graphics card specifications: Memory - 16GB GDDR6 Generation 256-bitCore frequency - up to 2360 MHz (in boost)Consumption - 300W (nominal)Technical process - 7nmNoise level - from 40 dB Of course, everyone is interested in the hashrate of the 6800 XT video card on air. So how many megahashes does the 6800 XT (6900XT hashrate) give? The card is capable of delivering 59 Mh / s on the Ethash algorithm in stock, while consumed - 235 Watts!

At a cost of a video card of 100,000 rubles, its payback will be approximately 310 days. Cost and ROI data are based on August 2021. You can calculate up-to-date information yourself by dividing the cost of the card by the profit from mining in rubles per day. How to increase hashrate 6800 XT by overclocking The hashrate of 6800XT can be much higher than stated. It is better to overclock the GPU for mining with MSI Afterburner. The utility interface is very simple. To overclock the video card, we need two sliders: Core Clock - overclocking by the core, increases the core frequency;Memory Clock - memory overclocking, increases the memory frequency. You need to change the frequency values little by little. Then test the stability of the work. If all is well, then you can increase the frequency even more. If the video card starts to malfunction or the drivers crash, then just reduce the frequency and that's it. There will be no harm. Optimized mining settings to increase the RX6800 XT hashrate: Core frequency: 1400Voltage per core: 881 mvMemory frequency: 2150 As for other algorithms, on the RX 6800 XT, mining hashrate can achieve the following indicators: CuckooCycle: 7.9 G / sKAWPOW: 28.6 MH / sOctopus: 36.5 MH / sZHash: 88 Sol / s For all of the above algorithms, the power consumption plus or minus one is 175 watts. Conclusion Considering the hashrate of the 6800 XT, the video card is very good at mining. It's not a bad card, with a great build and average cooling system. AMD has really stepped forward in card power. However, despite the fact that the RX 6800 copes well with loads, the same cannot be said about the older brother XT. We examined the features of the RX 6800 XT card: how many megahashes it produces on the air, the peculiarities of working with different algorithms and overclocking parameters. This information will help you effectively use the GPU for mining coins. Ethereum mining RX 6800 and RX 6900 XT specs: hashrate, profitability and performance AMD launched the RX 6000 series of cards to compete with the NVIDIA RTX 3000 series in terms of price and performance. Let's see what they did and if these cards can be used for mining.
