AMD Ryzen 7 1800X Review and Test: Return of the King

More than 5 years have passed since the announcement of Bulldozer architecture processors, and this time can be called “five years of silence”. The virtual absence of competition in the desktop and server segments has led to the fact that the annual increase of 5% in performance and the price of $1000+ for HEDT processors no longer surprised anyone, and minor changes in the competitor’s processor architecture deprived users who bought Sandy generation processors back in 2011 Bridge, it makes sense to replace the computer base – either a small performance increase or a high price. But AMD did not give up and after the not entirely successful launch of the Bulldozer line, engineer Jim Keller returned to its ranks, under whose strict guidance the legendary AMD K7 and K8 were designed, which made the processor revolution in the early 2000s.

And the efforts of engineers were not in vain – the new architecture found itself in processors code-named Ryzen. Today we will look at the key features and performance of these solutions using the example of the top representative of the Summit Ridge family – AMD Ryzen 7 1800X.

Introduction to Zen architecture

AMD Ryzen desktop processors are manufactured to 14nm process standards using FinFET transistors.

These processors consist of two quad-core modules (CCX) within a single die.

Thus, we have 8 active cores in Ryzen 7 with 16 MB of L3 cache (8 MB per module).

This arrangement allows you to implement multi-core server solutions by combining CCX. To reduce latency when using this method of combining, a special high-speed Infinity Fabric bus based on HyperTransport technology is used. The implementation of quad-core processors is based on disabling existing cores. Determining the range of processors is quite simple:

The new architecture is equipped with a dual-channel DDR4 memory controller; the processors do not have DDR3 support (but is it needed?).

As we can see from the slides provided, peer-to-peer RAM (according to information on the Internet – preferably with Samsung chips) takes precedence in performance for Ryzen processors.

The crystal also includes PCI Express 3.0 controllers (24 lanes, up to 16 lanes per video card), two SATA 6 Gb / s ports and USB 3.1 first generation for four ports. This allows processors to operate without additional processor logic, for which X300/A300 socket motherboards will be released. By the way, for the performance of Ryzen processors, motherboards with the new AM4 socket will be required, there is no compatibility with previous generations of motherboards.

Remarkably, AMD, having set itself the task of increasing the number of instructions per clock by 40%, not only coped with it, but also exceeded its expectations.

The performance of the cores has been increased by one and a half times! For AMD, this is not just a step forward – it’s a breakthrough. In addition to this, the SMT technology (Simultaneous Multi-threading, simultaneous multithreading) was implemented, which performs the functions of the closest analogue (Intel Hyper-Threading) – the execution of two-threaded operations on a single core. Separate execution units for each Ryzen core, its own cache for each core, and other optimizations indicate that the engineers sought to find compromises for the sole purpose of making the fastest and most technologically advanced processor in the history of the company. And the promising areas of application of these developments can be called wide:

This jump in performance is in harmony with the low heat dissipation: the nominal level of the Ryzen R7 1800x processor is declared at 95 W, while its predecessors in the face of the FX line have it at 220 W. This is facilitated by the transition to the 14-nm process technology and the use of the latest AMD developments. For example, a suite of technologies dubbed AMD SenseMI introduces fundamentally new capabilities.

Pure Power Technology : Quiet operation of the processor without excessive heat generation is ensured by artificial intelligence, built-in sensors and an optimized chip design.

  • Monitors temperature, performance and voltage;
  • Adaptive control works in real time, reducing power consumption;​
  • Continuous monitoring helps other AMD SenseMI technologies work.

Precision Boost Technology : Processor performance is adjusted in real time to match the load demands of your games and applications.

  • Works in conjunction with Pure Power Technology to optimize performance;
  • Dynamic adjustment of the clock frequency without stops and resets of the command queue;
  • High precision tuning in 25 MHz steps.

Extended Frequency Range Technology :​An additional automatic performance boost for gaming PC users with premium cooling solutions.

  • ​The processor frequency can be raised well above the normal limit of the Precision Boost technology;
  • Increased clock speed with highly efficient cooling system: traditional air cooler, water cooling or liquid nitrogen;
  • Fully automated system that does not require user intervention.​

Neural Net Prediction Technology : Built-in artificial intelligence allows the processor to run your applications more efficiently.

  • Artificial neural network inside every Ryzen processor;
  • Creates a decision model based on monitoring the executing code;
  • Anticipates what to do next, preloads instructions, chooses the best path for instructions through the processor.​​

Smart Prefetch Technology : learning algorithms that predict and prefetch required software data into cache memory to speed up calculations and minimize response time.

  • ​Predicts the location of the data that will be required in the future according to the software code;
  • Sophisticated prefetching algorithms that self-learn during software operation;
  • Preloads important data into a local cache, making it immediately ready for use.​

The processor architecture provides support for AES, AVX, FMA3 and AMD Virtualization technologies.

In addition to the above, AMD has introduced a series of processor coolers that will be bundled with BOX versions of Ryzen processors.

All in all, this looks great. Let’s take a closer look at AMD Ryzen 7.

AMD Ryzen 7 Lineup

The lineup includes three processors: AMD Ryzen 7 1700, 1700x and 1800x.

These processors have 8 processing cores with SMT technology, which allows processing up to 16 threads. The multiplier of all processors is unlocked. The main difference, besides the price, is in the declared heat pack, base and boost frequencies, and the availability of XFR technology in the 1700x and 1800x processors, which allows you to go beyond the declared turbo mode under favorable temperature conditions. In practice, this increase in frequency does not exceed 100 MHz in normal mode under the condition of a single-threaded load.

AMD’s price-performance ratio only confirms internal guesses – the top pick in the lineup is the Ryzen 7 1700 processor:

At the same time, according to this parameter, ADM puts its competitor in an awkward position. But demagogy and beautiful slides are one thing. It is necessary to find their confirmation in real test situations.

AMD Ryzen 7 1800x и X370

The hero of today’s review is the top processor in the Ryzen 7 line.

The cover almost completely covers the processor. Given the presence of solder under it, this will provide excellent heat dissipation.

Old traditions have not changed – AMD uses the PGA-performance of Ryzen processors. The number of legs increased to 1331 (40% more than its predecessors) led to a decrease in their thickness. You need to be more careful.

Design changes also affected motherboards – in addition to the new socket connector, we also have a slightly modified near-socket space. AM4 brings us differently positioned holes for mounting CPU coolers, compatibility with older mounts is not. It is worth noting that many manufacturers of cooling systems are already supplying sets of new mounts, and ASUS has gone further – it has released motherboards with universal holes, allowing the use of Socket AM3(+)/FM2(+) mounts.

The declared base frequency is 3.60 GHz, in turbo boost mode – 4.0 GHz, and all this with a TDP of 95 W.

The processor instance that participated in the testing reached a frequency of 3700 MHz with a multi-threaded load .

The voltage recorded by the CPU-Z and HWInfo programs reached a shocking 1.54 V at the peak. Using the Master Professional M890G multimeter at the control points, it was decided to check the correctness of the data obtained. At peak loads, the voltage did not exceed 1.45 V, however, it remained quite high. Considering that work on the BIOS of motherboards continues, it is worth checking what voltages are set at the factory settings, since overestimation can cause excessive heating.

With the help of XFR technology, under single-threaded loads, the processor multiplier of the loaded core increased to 41:

In idle, the processor frequency dropped to 2200 MHz, the voltage dropped to 0.8 V (voltages of 0.4 V were periodically recorded, the multimeter confirmed this).

The RAM frequency reached 2133 MHz with primary timings of 15-15-15-36 CR2.

The Prime95 program was used to test stability and temperature conditions. During the 35 minutes of the stress test, the frequency of all cores did not fall below 3700 MHz, and the temperature of the cores did not exceed 65 ° C. The HWInfo program recorded the maximum processor consumption of 101 W, the average was 90 W. Excellent result.

AMD Ryzen 7 1800X Processor: Overclocking

Given the base frequencies of the Ryzen 7 1800x, it was not possible to achieve something unexpected and supernatural. Dual-rank RAM with SK Hynix microcircuits aggravated the situation somewhat. If the processor was absolutely stable at a frequency of 4000 MHz with a set voltage of 1.48V, then the overclocking of the RAM cannot be called successful – only 2666 MHz was achieved with timings of 14-14-14-28 CR1. Attempts to set a higher frequency led to a cyclic shutdown and power on of the computer with a reset to factory settings. This should be attributed to the underdevelopment of the BIOS of motherboards, because compatibility problems with RAM were promised to be fixed in future versions of the microcode.

Under the far from the most powerful processor cooler, the processor did not heat up above 85 ° C, according to HWInfo64.

With a slight change in the frequency of the base oscillator, 4120 MHz was achieved at 1.526 V.

However, the peculiarities of such overclocking led to random computer freezes in the 3D application mode (most likely due to the connection of the base generator with PCI-E), so this mode was not used.

Another feature of Ryzen processors is the AMD Ryzen Master program, designed to overclock the presented processors in the operating system.

It is noteworthy that the step of the set frequency is 25 MHz. The functionality of the program will allow you to find the overclocking limit of your processor without rebooting and manipulating the BIOS.

We did not dare to test the stability in Prime95 at 1.48 V due to security reasons, using a multiplier of 39x (3900 MHz) and 1.4 V. In this mode, the processor warmed up to 75 ° C without resetting the frequency .

Test Methodology

Testing took place in modern games (carried out on all benches) and synthetic tests (carried out on benches with Ryzen 7 1800X and i7-5960x).

In games without a built-in test application, the minimum and average fps readings were recorded using the Fraps program with the following settings:

Game tests with one installed video card were carried out at 1920×1080 with maximum graphics settings, for systems with two video cards in SLI mode – at 2560×1440 and 3840×2160 (set via DSR) without changing graphics settings, except for anti-aliasing.

Synthetic tests

AMD itself opposes this processor to the Intel Core i7-6900K with a twofold difference in price (based on Cinebench R15 results)

Therefore, the comparison of the Ryzen 7 1800x will take place with the closest competitor in terms of declared performance – the Intel Core i7-5960x.

In synthetic tests, the following results were obtained:

Ryzen R7 1800x in synthetic tests is at a high level, both in the load on a single core, and in multithreading. With the i7-5960x running at higher core and RAM frequencies, the raw CPU performance is amazing. There is a question about the performance drop in WinRAR and Firestrike combined and graphics tests with two video cards installed. The first application appears to be optimized for Intel processors, and we may see code fixes in the future. In Firestrike, the dependence of graphic scores on the frequency and timings of RAM was carried out:

Fast memory with low timings could improve the situation in FHD resolution, as the performance of AMD Infinity Fabric depends on it. Unfortunately, at the time of testing, such memory was not available.

Separately, I would like to note the implementation of SMT technology. Judging by the results obtained in Cinebench R15, the efficiency of this technology is superior to Intel HT.

Testing in AIDA64 gave the following results:

The high speeds of the L2 and L3 caches in the 1800x are combined with high memory latencies and low transfer rates in L1.

Test results in SLI mode:

Conclusion

What can I say – AMD is competitive again. Before us is a fundamentally new architecture that has the prospect of further development, which allows Ryzen 7 processors to compete with the Intel HEDT platform in computing power already at this stage. Let the processors have slightly different capabilities (the top Ryzen 7 1800x does not have a four-channel RAM mode, only 16 PCI-E lanes for video cards, L3 cache 8 + 8 MB), but it is worth considering that they also have a different price league: today’s hero review is 2 times cheaper than a competitor.

The jump in the number of operations per second (IPC) allows Ryzen processors to look decent under a single-core load, SMT technology to achieve a high level of performance in multi-threaded operations. All this is accompanied by both a low level of consumption compared to Intel HEDT, and acceptable temperatures.

But the emergence of a new architecture brings problems. No matter how much we tried to delay testing, it was not possible to wait for the full correction of known deficiencies. Poor compatibility with non-Samsung dual rank RAM, lack of Windows Scheduler fixes, issues with some SMT-enabled applications. One feels the “dampness” of the BIOS of motherboards, but the manufacturers promise to fix everything. The work, as they say, is endless, because due to the almost complete absence of competition, all optimizations were carried out for Intel processors. This gives hope for a brighter future – already now for some programs and games there are fixes that increase the speed of Ryzen processors. Considering, that the gaming performance of the tested Ryzen R7 1800x differs slightly from Intel processors, things will only get better in the future. For those who are going to do rendering, video editing and other multi-threaded tasks, the 1800x will be an excellent choice for its price. On the other hand, the Ryzen R7 1700 looks even more attractive, and those who know what they are paying for will make the right choice.

Based on the results of the review, I would like to note the following features and disadvantages of the Ryzen R7 1800x processor.

Pros: Advantages

  • A large number of operations performed per second;
  • Eight full-fledged processor cores;
  • Third level cache (8+8 MB);
  • The presence of SMT technology, which allows processing up to 16 streams;
  • Low cost relative to competitors;
  • Low consumption compared to previous generations of processors;

Minuses: Disadvantages

  • Low overclocking potential;
  • Problem with overclocking RAM;
  • A small number of PCI-E lanes for video cards;
  • Dampness of drivers, BIOS of motherboards and optimizations for applications and games.

I would like to wish AMD success in correcting these shortcomings. We know that they are good at it (as it was with the Radeon RX 4×0 at the start of sales and six months after them). We also promise to monitor the performance of Ryzen architecture processors depending on the appearance of new patches for games, drivers and BIOS versions.

Thank you for attention!
