Zen 4 ddr59/6/2023 ![]() Could Tom's have the list of motherboards from the 300-series chipsets that do support Ry5K? That would actually help track which partners are indeed reliable and can be trusted with buying into AM5. Plus, we all know which motherboard vendors actually followed through with the updates, so they'll get more sales once B650 launches. Maybe partners would rather convince you to buy a new motherboard, but allowing this "mix and match" with generations does help overall sales or so it is my impression. This being said, after AM4, I'd imagine both AMD and partners have seen it does matter they do keep supporting newer CPUs and see that as a strength. The huge caveat is you have to trust not only AMD, but the partners to go with it and roll the BIOS updates down the line. One small point that I won't really defend much, but buying into the AM5 platform, you buy into several years of support. I hope AMD can alleviate it a bit so they become more of a mainstream crowd fav. ![]() Good to see more reaffirmation these CPUs don't have a performance problem, but a platform cost (or "cost of entry") problem with them. Nvidia GeForce RTX 2080 Ti FE - Application testsĢTB Sabrent Rocket 4 Plus, Silverstone ST1100-TI, Open Benchtable, Arctic MX-4 TIM, Windows 11 ProĪll configurations with overclocked memory also have tuned core frequencies and/or lifted power limits. Gigabyte GeForce RTX 3090 Eagle - Gaming and ProViz applications This also automatically enables the AMD-recommended Auto setting for the fabric and a 1:1 ratio for the memory frequency and memory controller (Auto:1:1 is the recommended setting for memory overclocking with Ryzen 7000).Ĭore i9-12900K and Core i5-12600K Test System Configurations AMD Socket AM5 (X670E) ![]() For our overclocked configurations, we enabled the DDR5-6000 EXPO profile for the memory kit. Our overclocks were rather straightforward - we enabled the auto-overclocking Precision Boost Overdrive (PBO) feature with 'advanced motherboard' settings and adjusted the scalar setting to 10X. We also tested with secure boot, virtualization support, and fTPM/PTT active to reflect a properly configured Windows 11 install. We tested all Intel configurations with DDR5 memory, but you can find performance data for DDR4 configurations in our CPU Benchmark hierarchy. We tested the Ryzen 7000 processors with an ASRock X670E Taichi motherboard. Ryzen 9 7950X and Ryzen 5 7600X Benchmark Test Setup However, as we saw in the single- and multi-threaded y-cruncher benchmarks, this performance doesn’t scale linearly to higher core loadings. The y-cruncher and Geekbench 5 crypto scores experience rather disproportionate gains, but that comes as a result of Zen 4’s support for AVX-512. As you can see, Zen 4 does deliver solid IPC improvements in a multitude of workloads. We tested a limited subset of single-threaded workloads to see the clock-for-clock improvements, locking all chips to a static 3.8 GHz all-core clock with the memory dialed into the officially supported transfer rate. As we saw in our own benchmarks, the approach provides significant performance uplift. AMD says AVX-512 provides a 30% increase in multi-core FP32 workloads over Zen 3 and a 2.5X speedup for multi-core int8 operations. Given that we're looking at a much denser N5 process for Ryzen 7000 compared to the 7nm process for Ryzen 5000, the smaller die has 6.5 billion transistors for the Zen 4 CCD compared to 4.15B transistors for Zen 3 CCDs (a 36% increase for Zen 4).ĪMD’s implementation results in lower throughput per clock than Intel's method, but the higher clocks obviously offset at least some of the penalty. Additionally, the Zen 4 compute die (CCD) measures 70mm^2, which is somewhat smaller than the 83.74mm^2 die on the Ryzen 5000 processor. ![]() Speaking of the die, the die size for the new 6nm I/O die (IOD) is 122mm^2, or roughly the same size as the 124.94mm^2 12nm IOD present on the Ryzen 5000 chips. This approach also saves die area and defrays the frequency and thermal penalties typically associated with Intel's processors when they execute AVX-512 workloads. However, this provides compatibility with AVX-512 and still boosts performance. This means that it actually takes two clock cycles to execute an AVX-512 instruction. AMD describes its AVX-512 implementation as a 'double-pumped' execution of 256-bit wide instructions. ![]() AMD has enabled support for AVX-512 instructions, giving it a curious advantage over Intel, which pioneered the SIMD instructions but ended up disabling them with Alder Lake. ![]()
