For context, that still puts the 7800X3D well ahead of the last-gen 5800X, by a 16 percent margin versus the 5800X3D we're looking at nearly 25 percent better multi-core performance. That doesn't sound great, but it's a relatively minor performance penalty given the large uptick in gaming performance we expect to see later. That corresponds to the 7800X3D scoring 706 for single-core and 7108 for multi-core in Cinebench R20 compared to 7 respectively for the 7700X. In the single-core and multi-core results, we see about 10 percent faster results on the 7700X versus the 7800X3D, which has the same basic eight-core, 16-thread design as the new chip but at higher frequencies as it doesn't need to accommodate the 3D V-Cache. These results are useful even in a gaming context as they set expectations for both single-core and multi-core performance in scenarios where the extra cache provides no advantage - and you may well want to occasionally export a video clip of your sick Counter-Strike 2 clutches. That means BIOS version version for the ASRock X670E Taichi motherboard that hosts our AMD processors and BIOS revision F8a for the Z790 Aorus Master board socketing the 13900K.īefore we get into the gaming benchmarks that make up pages two to six, let's quickly run through some quick content creation benchmarks: a Cinebench R20 3D render and a Handbrake video transcode. We've previously used an older version of Windows, 21H2, to maintain compatibility with past benchmarks, but this time we've thrown out the old results and tested afresh - with the latest Windows updates, chipset drivers and BIOS revisions installed. Our rig was completed with a 1000W Corsair RM1000x power supply. Cooling is provided by a 240mm Alphacool Eisbaer Aurora AiO, which is happily still compatible with the AM5 socket.įor storage, we're using three PCIe 4.0 NVMe SSDs to hold all of our games - a 4TB Kingston KC3000, a 1TB PNY XLR8 CS3140 and a 1TB Crucial P5 Plus. That means an ASRock X670E Taichi motherboard, G.Skill Trident Z5 Neo DDR5-6000 C元0 RAM and Asus' RTX 3090 Strix OC for our graphics card.

There's also DDR5 and PCIe 5.0 support, with 5nm CCDs and a 6nm I/O die, alongside the new AM5 socket which unlocks additional power and performance - albeit with the requirement of a new motherboard, new RAM and potentially new cooling. As a reminder, each of these Ryzen 7000 desktop designs benefits from a range of advances over their Ryzen 5000 (Zen 3) counterparts, with a quoted 13 percent uptick to instructions-per-clock (IPC) and more internal improvements, like an improved execution engine and a better branch predictor. You can see how the 7800X3D fits into AMD's Zen 4 lineup in the table below. The simpler design is less flexible, but has its advantages too. Under the skin, the eight-core 7800X3D resembles the 12-core 7900X3D and 16-core 7950X3D - with just the 3D V-Cache chiplet enabled. It's a similar story to the Intel Core i9 13900K, a fantastic gaming and content creation CPU - but one that relies on scheduling algorithms built into Windows to make full use of its asymmetric performance core and efficiency core design.Įven getting close to its rivals in terms of frame-rate could put the 7800X3D in the same hallowed tier as the legendary 5800X3D, a reasonably affordable mid-range CPU that punches well above its weight and even challenges Intel's equivalent-generation flagship parts. By comparison, the 7950X3D and 7900X3D released in February split that power budget across two chiplets, only one equipped with the extra 元 cache, so we could potentially see even greater performance than these CPUs. Our expectations for the 7800X3D are high - after all, the CPU's design permits its full 120W TDP to be dedicated solely to an eight-core chiplet complete with performance-boosting 3D V-Cache. To find out which of these three options is the fastest gaming CPU on the market, we've started a shootout - and tested each option fresh in nine of the most challenging CPU-limited scenarios, from modern games that soak all available threads to ray tracing showcases and esports titles. The $449 Ryzen 7 7800X3D processor promises to deliver similar gaming performance to AMD's flagship 7950X3D and Intel's Core i9 13900K, while consuming less power and costing significantly less than its rivals. ![]() The one that we've been waiting for is here.
