AMD Ryzen 9 7950X and Ryzen 7 7700X review: maximal design

Following on from our Ryzen 9 7900X and Ryzen 5 7600X overview, it is lastly time to have a look at the 2 remaining CPUs in AMD’s Ryzen 7000 household: the $449/£439 Ryzen 7 7700X, a possible gaming worth champ, and the $799/£769 Ryzen 9 7950X, a sixteen-core titan anticipated to outperform nearly each client CPU in content material creation workloads. We have seen important worth cuts on Ryzen 7000 processors since launch – so are these CPUs value shopping for in 2023?

As a fast recap, these Zen 4 processors are profoundly completely different from AMD’s last-gen Ryzen 5000 components. There’s been a shift to a brand new socket, AM5, with an LGA design that may present as much as 230W of energy, in addition to a brand new 6nm I/O die, built-in graphics on all fashions and assist for 2 key applied sciences: DDR5 and PCIe 5.0.

These upgrades unlocked some spectacular gen-on-gen beneficial properties within the case of the 7600X and 7900X, and there is the potential for even better enhancements with the 7700X and 7950X. As AMD makes use of a chiplet-based design with as much as eight cores per CCD, the eight-core 7700X and sixteen-core 7950X must signify the utmost efficiency doable from single-CCD and double-CCD designs respectively – and stories recommend that in some titles, the efficiency penalty of splitting a gaming workload throughout a number of CCDs may counteract the beneficial properties from getting access to the next variety of threads, leaving the 7700X as a CPU of explicit curiosity.

Watch the newest DF Weekly, the place Digital Foundry workers talk about the most popular gaming know-how information.

You may see how every of the designs stack up within the desk beneath. With a quoted 13 p.c uptick to instructions-per-clock (IPC) and extra inside enhancements, like an improved execution engine and a greater department predictor, we would anticipate the numerous boosts to frequency and better energy allowances to translate into some critical efficiency beneficial properties in all method of workloads, from gaming to content material creation. That was definitely the case for the 7600X and 7900X – so how do the 7700X and 7950X fare?

To seek out out, we’ll be utilizing the identical take a look at system that featured in our earlier Ryzen 7000 assessments – an ASRock X670E Taichi motherboard, G.Ability Trident Z5 Neo DDR5-6000 CL30 RAM (with Corsair Dominator Platinum DDR5-5200 for supplementary testing) and Asus’ RTX 3090 Strix OC for the GPU aspect of issues. Cooling was supplied with a 240mm Alphacool Eisbaer Aurora AiO, which is fortunately suitable with the brand new AM5 socket.

For storage, we’re utilizing three PCIe 4.0 NVMe SSDs to carry all of our video games – a 4TB Kingston KC3000, a 1TB PNY XLR8 CS3140 and a 1TB Essential P5 Plus. Our rig was accomplished with a 1000W Corsair RM1000x energy provide.

Be aware that we’re utilizing an older model of Home windows 11 right here, because the 22H2 replace appears to have resulted in poorer efficiency for Ryzen 7000 processors. That, mixed with a BIOS replace for our motherboard, meant retesting the 7600X and 7900X to make sure our outcomes have been nonetheless legitimate – and we did see small adjustments in lots of video games.

Elsewhere, we used an Asus ROG Crosshair 8 Hero for Ryzen 5000 testing, an Asus ROG Maximus Z590 Hero for Eleventh-gen Intel testing, an Asus ROG Z690 Maximus Hero for Twelfth-gen testing, and a Gigabyte Z790 Aorus Grasp for 13-th gen testing; all of those are high-end boards for his or her respective platforms. DDR4 motherboards used G.Ability 3600MT/s CL16 reminiscence, the sweetspot for DDR4, whereas DDR5 motherboards used DDR5-6000 CL30 as famous beforehand.

Earlier than we get into the gaming benchmarks that make up pages two to 5, let’s set the scene with some fast content material creation benchmarks: a Cinebench R20 3D render and a Handbrake video transcode.

As anticipated, the 7950X is the one to look out for within the content material creation stakes, with report excessive scores within the Handbrake h.264 and h.265 (HEVC) transcode assessments – albeit solely by a comparatively slender margin over the Core i9 13900K, lower than one p.c in h.264 and round 10 p.c in h.265. Within the Cinebench take a look at, a historic energy for AMD Ryzen designs, it is the 13900K that retains the highest spot by round 5 p.c, however the 7950X remains to be considerably quicker (~46 p.c) than the 5950X, for a formidable gen-on-gen enhance.

The 7700X additionally exhibits clear development from the 5800X, AMD’s first eight-core design from the Zen 3 era. Right here, each single and multi-threaded scores as examined in Cinebench improve by just a little underneath 30 p.c, which might make for an important gaming efficiency uplift. Handbrake efficiency can also be stronger by an identical margin, though final gen’s 5950X nonetheless presents higher efficiency total because of its increased core and thread depend – and this older CPU is now cheaper than the 7700X, making it a more sensible choice for content material creation if not for gaming.

The facility figures are additionally value taking a look at right here. We’re solely testing on the wall, and we do have completely different motherboards and RAM in play, however you’ll be able to nonetheless see there is a pattern in direction of increased wattage counts within the newer CPUs, with the last-gen 5950X and current-gen 7600X drawing across the identical quantity of energy (~236W) – whereas the 7950X jumps to 368W. That is nonetheless considerably lower than the 13900K, which peaked at 473W through the HEVC encode whereas delivering a barely worse rating. So the brand new AM5 socket is definitely able to delivering extra energy, however in broad strokes it seems that AMD’s Zen 4 design remains to be extra power-efficient than its nearest Intel equal. That ought to make cooling barely much less of a priority, and positively comes as a aid in a time when GPU wattage can also be climbing quickly on flagship-grade playing cards.

Now, let’s get into the enjoyable stuff – the video games. We have examined a variety of titles, so select your favourites from the hyperlinks beneath or simply hit that subsequent web page button to proceed the journey.
