Description
The 7900X looks a bit more competitive from a value perspective in Premiere Pro, costing just 9% more than the 7700X when looking at price to performance. It's also much better value than the competing Intel parts. That said, if performance is the ultimate goal then paying the premium for the 7950X will be worth it. What We Learned To tie a bow on it, if you're genuinely in the market for a new processor at this moment and you want the best for gaming, the Core i9 12900K is that and more. The Z690 platform offers the only way into the most cutting-edge technologies around today, and for PC builders in 2021, it's sure nice to know you won't be falling behind the curve in 2022 once PCIe 5.0 and DDR5 are more widely adopted. F" means it requires discrete graphics. In other words, it doesn't have integrated graphics (basically a GPU built into the processor), thus requiring a standalone graphics card. As I said before in our previous comparison, Intel’s 14th Gen Core processors (Raptor Lake-S) isn’t really a “Next-Gen” but rather a “Refresh” of their previous 13th Gen Raptor Lake processors. Each P-Core has access to 1.25MB of L2 cache. From there, they're hooked up to 30MB of Intel Smart Cache, which is also shared between E-Cores and onboard integrated graphics (disabled in KF-series chips).
Office and web applications are typically single-threaded, so running a single application won't take advantage of a many-core CPU. The Efficient Cores are built on the Gracemont architecture, whose origins are in the Atom lineup. Traditionally built for lower-power, lower-performance processors, Intel has decided that its Atom architecture may find a use in more powerful processors after all, and the Core i9 12900K features eight Gracemont Efficient Cores in total.
As was the case with the 7950X, the 7900X is a bit broken in The Riftbreaker. Realistically it would be able to match at least the 7600X, if not the 7700X, but as we saw with the 7950X this game has an issue with the dual CCD design of the 12 and 16-core models, and this is something AMD is in talks with the developer to try and solve. AMD has stressed that this behavior is intended and that it's important to note TJMax is the maximum safe operating temperature – not the absolute maximum temperature. In the case of Zen 4, the processors are designed to run at TJMax 24/7 without risk of damage or deterioration. At least AMD's AM4 platform offers plenty of cheaper motherboards today, something we may have to wait around for a bit longer to see from Intel's board partners. Counter-Strike: Global Offensive has no surprises for us. The 7900X was a whisker faster than the 7950X with 518 fps and that made it 15% faster than the 12900K, a convincing win there. 12 Game Average Performance
For AMD, that would appear to be its 3D V-Cache processors, which it says are already in production and should improve gaming performance by up to 15%. If you scan over my benchmarking numbers, that has the potential to once again give AMD a lead in many games. But these chips are going to have to deliver a significant boost to compete at their current prices, and for once it's AMD in the hot seat to justify its premium pricing rather than the other way around. I haven’t tried the so-called 6GHz boost “right out of the box”… I shouldn’t need to! When I buy a product, it expect it to run at the default speed and that should be good enough. However, my motherboard allows safe AUTO Turbo Boost to 5.5GHz and 5.8GHz, which is just fine by me. By Turbo Boosting to 6GHz, you better make sure you have sufficient cooling that can handle those high temperatures. Next up we have F1 22 and like the rest of the Zen 4 lineup the 7900X is impressive in this title, delivering similar performance to what we've already seen from the 7600X, 7700X and 7950X. Based on our evaluation of using Intel's Core i9-12900K CPU for gaming, you can expect excellent game performance with a high-performance CPU cooler.Tiny Tina's Wonderlands is not a very demanding game on the CPU side, but it remains a good indicator of how many modern games are going to be GPU bound, even when using an RTX 3090 Ti at 1080p as we see in this test. It's a similar story with the Corona benchmark, the 7900X was 26% slower than the 7950X but 13% faster than the 12900K and a massive 28% faster than the old 5900X. As we found with the 7950X, the single thread performance of the 7900X is very strong, producing a score of 2034 pts. That's not a big improvement over the 12900K, a mere 3% difference, but it does mean the 7900X is often going to have the upper hand for productivity workloads given it's faster in Cinebench R23 for both multi and single core performance. The first thing we did was update the BIOS on the Unify motherboard to the latest available version. Since this article is more about testing the CPU performance, we primarily tested in Cinebench and AIDA 64, rather than any PC game benchmarks that are more focused on GPU performance. Here the 7900X doesn't look great when including platform costs, it's slightly worse value than even the 12900K and considerably worse value than the 7700X and 7600X. Clearly, if you're just gaming the 6 and 8-core Zen 4 CPUs are far better value.
