After an hour of load testing, the CPU maintained an all-core frequency of 5.1 GHz on the primary CCD1 and 4.9 GHz on the secondary CCD2, so there's a 4% frequency discrepancy between the two core complex dies. Here's a look at the Ryzen 9 7950X's clock behavior in Cinebench R23. All testing was conducted using the GeForce RTX 3090 Ti, Windows 11, and Resizable BAR enabled for all configurations. The new AM5 test system is based on the MSI MEG X670E ACE, for which we followed AMD's guidelines to use the supplied DDR5-6000 C元0 memory. Then for the 12th-gen Alder Lake CPUs we've tested using DDR4-3200 dual-rank CL14 memory and DDR5-6400 single-rank C元2 memory and we have from the Core i3-12100 up to the Core i9-12900K for comparison. We have included important Intel 10th-gen Core series models but due to time constraints we decided to skip the 11th-gen. There's a lot more to go over and a ton of testing and benchmarks as usual, we've been busy over the past few weeks updating all our CPU data and as a result we have 17 CPUs for comparison.įor the AM4 platform we've got a range of Zen 2 and Zen 3 CPUs with popular models such as the Ryzen 9 3950X, Ryzen 7 5800X, and of course, the 5950X is also included, but there are half a dozen more models also included. The Ryzen 9 7950X is set to replace the well-regarded 5950X, but quite surprisingly the launch price or MSRP has been dropped from $800 the previous generation to $700 for the 7950X - that's a healthy 13% discount for what should be a much faster processor.īargain shoppers and current AM4 owners will want to know though that at present the 5950X can be had for as little as $550, so the newer Zen 4 16-core model is coming in at premium, of course. Compared to the mainstream 7600X, the TDP is increased from 105w from a single CCD to a whopping 170w, though do note because the same I/O die has been used the same 28 PCIe 5.0 lanes are supported. In case you missed it, we already checked out the 6-core Ryzen 5 7600X yesterday, with the 7700X and 7900X reviews coming over the next few days. The additional CCD compared to more affordable Ryzen models means the total 元 cache capacity is increased from 32MB to 64MB, and now there's a total of 16MB L2 cache. AMD's new Zen 4 flagship, the Ryzen 9 7950X is a 16-core, 32-thread CPU that clocks between 4.5 GHz and 5.7 GHz depending on the load, with two Core Complex Dies (CCD) along with a 6nm I/O die.
