Ryzen 9 7950X & Ryzen 7 7700X in the test: performance, efficiency, IPC, clock, iGPU and more analyzed

admin

AMD's Ryzen 7000 processors start with Zen 4 architecture. To start, ComputerBase traditionally took a close look at the Ryzen 9 7950X and Ryzen 7 7700X: The test with benchmarks in apps and games as well as IPC, clock, efficiency, UV and OC analyzes gives a comprehensive impression of the new generation.

    • AMD Ryzen 7000 in test

    24 hours before the start of sales on September 27, 2022, the embargo on tests of AMD's new processors fell. This test clarifies what the new generation can do in the usual detailed manner, including IPC, clock, efficiency, OC and UV analyses, extensive benchmarks, a look at the first iGPU in the Ryzen X series and much more.

    A small teaser right at the start

    Detailed benchmarks can be found on page 4 of this article, on pages 1 to 3 the architecture is first analyzed. However, the following teaser on the performance should make it clear right from the start: Ryzen 7000 is fast. Very fast.

    Startup with Ryzen 9 7950X and Ryzen 7 7700X

    ComputerBase had both the Ryzen 9 7950X and the Ryzen 7 7700X available for testing in advance. AMD's test kit also included the Gigabyte X670E Aorus Master (BIOS: 813b) and G.Skill Trident Z5 DDR5-6000CL30 RAM with AMD Expo Profiles for Ryzen 7000. Asus is also providing a ROG Crosshair X670E Hero WiFi and Corsair DDR5-6000CL30 Dominator Platinum RGB.

    This hardware was available for testing AMD Ryzen 7000

    How Ryzen 7000 was tested

    This made it possible to test and gain experience on two systems in parallel. Unless otherwise stated, all test results in this article were determined on the Gigabyte X670E Aorus Master, which proved to be slightly more powerful and slightly less power-hungry under full load.

    Tests were usually carried out with 2 × 16 GB DDR5-5200CL32 and standard specifications for TDP, PPT, ECD and TDC, but tests with DDR5-6000CL30 and higher CPU limits, manual OC and undervolting (less VCore) are also included in the article. Extensive use was made of the iGPU used for the first time in Ryzen desktop CPUs outside of the G series; a dedicated graphics card was only used for gaming and for power consumption measurements comparable to older tests.

    Ryzen 9 7900X and Ryzen 5 7600X to follow

    Unfortunately, attempts over the past few years to obtain the other two “stock keeping units” (SKUs) from other sources failed this year. After CPUs organized in this way were tested elsewhere at the beginning of 2022 without concealing their origin, and this was not without consequences, unfortunately nothing could be done about it. AMD's Ryzen 9 7900X and Ryzen 5 7600X models can be expected shortly.

    Model variants and prices (RRP) at the start

    ComputerBase already reported extensively on Ryzen 7000 and the new AM5 platform for the final presentation at the end of August 2022. Essential information on the new architecture, the new Socket AM5, the new chipsets X670E, X670, B650E and B650 as well as DDR5 including AMD Expo as a competing technology for Intel XMP can therefore already be found elsewhere:

    The core of what follows is an analysis of the new CPU and platform generation, although the Also good to know section contains some additional information from the AMD Ryzen Tech Day, which took place in Austin in August.

    These are the RRPs for Germany

    Shortly before the market launch, AMD first named the RRPs of the four models Ryzen 9 7950X, Ryzen 9 7900X, Ryzen 7 7700 and Ryzen 5 7600X for Germany. Given the USD-EUR parity and the fact that MSRPs in the US are quoted without VAT that varies locally, the “euro surcharge” is not surprising. For an assessment of the price development compared to Ryzen 5000, a look at the US prices is more useful.

    First and foremost, the cheaper flagship is striking, but eight cores are also cheaper at the start of Zen 4 than at the start of Zen 3 – if you compare Ryzen 7 5800X with Ryzen 7 7700X. In comparison 5700X against 7700X, however, the price has increased significantly. Ryzen 9 7900X and Ryzen 5 7600X have not experienced any changes in the USA. The RRPs for Germany have all increased.

    Zen 4 vs. Zen 3: IPC, clock & Latency comparison

    A new CPU generation can increase performance compared to its predecessor via three starting points: more clock, more power per clock and more cores. With the Ryzen 7000, AMD has changed two of the three adjustment screws with the change from Zen 3 to Zen 4: Both the clock and the performance per clock (IPC) have increased, the number of cores per CPU class has remained the same.

    All Ryzen 7000 of the X Class come without a cooler, the larger box of the Ryzen 9 is filled with foam rubber

    Zen 4 vs. Zen 3: IPC comparison

    According to AMD, Zen 4 should not work 8 or up to 10 percent faster than Zen 3, as initially promised, but around 13 percent faster with the same clock – in the desktop environment. AMD itself spoke of optimizations in the last few meters, but basically wanted to leave the competitor in the dark for as long as possible. But the evaluation basis presented in the end was also different – ​​additional and benevolent applications were taken into account.

    Because the Cinebench result shown in early summer is from Zen with a presented increase of 9 percent 3 on Zen 4 with the same clock still the same. But other apps presented by AMD – including games in particular – sometimes scale much better, so that the manufacturer was able to name an average of 13 percent in the end.

    A comparison of the old and the new package

    As an introduction to the test, ComputerBase determined how significantly the performance of the new CPUs has increased compared to Zen 1, Zen 2 and Zen 3 as well as Intel Alder Lake, each with 3.6 GHz (Zen 1 does not do more). There is a blur: All CPUs were operated with DDR4-3200CL14, only the Ryzen 7000 ran with DDR5-5200CL32 – the platform no longer supports DDR4.

    IPC gain in the multi-core test course

    On average, Ryzen 9 7950X and Ryzen 7 7700X react 12 percent faster under multi-core load compared to their ” direct” predecessors Ryzen 9 5950X and Ryzen 7 5800X when all running at 3.6 GHz.

    Interesting: The Ryzen 7 7700X with 8 Zen 4 cores is tied at 3.6 GHz with the Core i9-12900K with 8 P cores (E cores were disabled for comparison).

    IPC gain in the single-core test course

    The increase in the single-core loads used by the editors for the Ryzen 5000 for the IPC comparison is less clear. Zen 4 is up 6 percent (Ryzen 7) or 7 percent (Ryzen 9) compared to Zen 3 – the large performance cores in Intel Alder Lake remain in the lead by 4 percent. AMD has their interaction better under control, otherwise the “multi-core IPC” would not be as high.

    With Ryzen 5000, it was the other way around recently: the CPUs increased more significantly in single-core loads than in multi-core scenarios .

    IPC profit in the game test course

    In games, the editors have an IPC profit of 11 percent (FPS) and 13 percent (percentile FPS) respectively. Intel Alder Lake remains in the lead with 5 and 6 percent, respectively, the Ryzen 7 5800X3D with the L3 cache attached even with 19 and 21 percent.

    Zen 4 vs. Zen 3: clock comparison< /h3>

    With Zen 4, more IPC per clock is only one side of the coin, the other is the clock itself. Just looking at the key technical data listed above makes it clear that the clock has increased significantly. But that doesn't have to be all.

    Ryzen 7000 can also clock higher

    After the clock disaster with Ryzen 3000, when many SKUs did not reach the promised maximum turbo clock rates, Ryzen 7000, like Ryzen 5000, takes a different path: In practice, the CPUs can, if temperature, load and other factors affecting the turbo allow it, clock even higher.

    Specifically, the Ryzen 9 7950X achieved up to 5,730 MHz in the editorial test, the Ryzen 7 7700X even up to 5,556 MHz – 156 MHz more than advertised . On average over a Cinebench R23 single-core run, the 7950X again hit the advertised clock exactly, while the Ryzen 7 7700X ran the entire benchmark with 156MHz more clock on the fastest core.

    The clock rates of the first two Ryzen 7000s in the editorial department are compared below in a single, multi-core and three game loads. In the Cinebench R20 single-core and in the games, it is the average maximum clock on the respectively fastest core in the benchmark, in the Blender benchmark (multi-core) it is the average clock across all cores in the benchmark. The results speak for themselves.

    The Ryzen 7 7700X clocked extremely high in the test

    Once again, the clock rates of the Ryzen 7 7700X are remarkable: With an average of 5,296 MHz in the Blender benchmark, the CPU is only 104 MHz away from the official maximum turbo in multi-core full loads and in all tested games are (as in the Cinebench single core) consistently 5,550 MHz – 150 MHz more than officially stated.

    Zen 4 vs. Zen 3: Cache and RAM latencies compared

    Cache and RAM latencies were a big issue with Ryzen 1000 and Ryzen 2000 with Zen or Zen+, which has receded into the background with the improvements in Zen 2 and Zen 3 (despite I/O die). Typical were Ryzen 5000 latencies of 0.8 ns, 2.5 ns and 10.x ns for L1, L2 and L3 cache.

    The cache at a glance (Image: AMD)

    On Ryzen 9 7950X and Ryzen 7 7700X, both L1 and L3 cache latency have continued to drop, with L3 cache progress is clear. The response time of the L3 cache, measured in clock cycles, has even increased from Zen 3 to Zen 4, but this is more than compensated for by the higher L3 cache clock.

    The memory latency has increased slightly, comparing DDR4-3200CL14 on Ryzen 5000 with DDR5-5200CL32 on Ryzen 7000. With DDR5-6000CL30, the sweet spot defined by AMD, Ryzen 7000 is also ahead in this respect.
