AMD’s Ryzen 7000 processors are right here, with a brand new 5nm course of node and AM5 socket unlocking increased clock frequencies, better energy utilization and in flip higher efficiency. The 4 new CPUs releasing on September 27th additionally embrace a brand new 6nm I/O die, built-in graphics and assist for DDR5 and PCIe 5.0 – it is a substantial characteristic improve that reclaims parity with Intel’s 12th-gen CPUs.

Of course, options usually come second to fps, so efficiency testing has comprised the bulk of our efforts. So far, two chips have crossed our desks – the $549/£579 Ryzen 9 7900X and $299/£319 Ryzen 5 7600X – and we have put them up towards our assortment of hand-picked video games and a sprinkling of productiveness benchmarks too. The query we would like to reply is easy: how do these Zen 4 designs carry out towards Intel’s 12th-gen Core counterparts and AMD’s older Ryzen 5000 lineup?

The transfer to DDR5 additionally brings up a secondary query – what’s the present RAM candy spot for worth/efficiency with Ryzen 7000? AMD recommend of their documentation that DDR5-6000 is the preferrred proper now, so we have examined their CPUs – and Intel’s closest equivalents – at each 6000MT/s (AMD’s advice) and 5200MT/s (the place we did our Intel 12th-gen testing).

Before we get into the outcomes of our CPU benchmarks, let’s take a short look below the hood to perceive what AMD has wrought right here.

Watch the newest episode of DF Direct Weekly, the place Digital Foundry workers talk about the hottest subjects in gaming know-how.

First up, AMD recorded a 13 p.c enchancment to IPC, directions per clock, thanks to a bigger L2 cache, an improved execution engine, a greater department predictor and different inside modifications. That ought to translate into an analogous quantity of single-core efficiency uplift at the identical frequency, so mixed with some substantial frequency enhancements and the shift to higher-clocked DDR5, Ryzen 7000 ought to provide a better-than-average generational enchancment.

The new AM5 platform can be fascinating. AMD has shifted from a ‘PGA’ to an ‘LGA’ design for his or her processors, which means that as a substitute of getting gold pins on the underside of the CPU, these at the moment are on the motherboard – so it is now a lot tougher to break a CPU, however simpler to break a motherboard. The pin depend has additionally risen considerably, permitting extra energy to be delivered to the CPU – up to 230W, with the Ryzen 9 designs transferring from a default TDP of 105W last-gen to 170W this-gen.

CPU design Boost Base L3 cache TDP RRP
Ryzen 9 7950X Zen 4 16C/32T 5.7GHz 4.5GHz 64MB 170W $699/£739
Ryzen 9 7900X Zen 4 12C/24T 5.6GHz 4.7GHz 64MB 170W $549/£579
Ryzen 7 7700X Zen 4 8C/16T 5.4GHz 4.5GHz 32MB 105W $399/£419
Ryzen 5 7600X Zen 4 6C/12T 5.3GHz 4.7GHz 32MB 105W $299/£319
Ryzen 9 5950X Zen 3 16C/32T 4.9GHz 3.4GHz 64MB 105W $799/£750
Ryzen 9 5900X Zen 3 12C/24T 4.8GHz 3.7GHz 64MB 105W $549/£509
Ryzen 7 5800X3D Zen 3 8C/16T 4.5GHz 3.4GHz 96MB 105W $449/£429
Ryzen 7 5800X Zen 3 8C/16T 4.7GHz 3.8GHz 32MB 105W $449/£419
Ryzen 5 5600X Zen 3 6C/12T 4.6GHz 3.7GHz 32MB 65W $299/£279

That places a better give attention to CPU cooling, however some present AM4 CPU coolers must also work on AM5 which is good for anybody that is invested in a high-end possibility. Basically, any cooler that screwed into the default AMD AM4 backplate also can screw into the new AM5 one, however designs that required a customized backplate to be put in aren’t appropriate. Thankfully, our take a look at rig makes use of Alphacool’s Eisbaer Aurora 240mm AiO, which does use the default AMD backplate and due to this fact we are able to keep cooler compatibility throughout the generations – good.

It’s additionally value mentioning the remainder of the take a look at rig we’re utilizing. AMD offered ASRock’s X670E Taichi motherboard, which supplies a plethora of M.2 slots, beefy energy supply and conveniences like on-board energy and reset buttons, and an LED readout for error codes and present CPU temperature.

This is mixed with high-spec G.Skill’s Trident Z5 Neo DDR5-6000 CL30 RAM, Corsair’s Dominator Platinum DDR5-5200 CL40 for supplementary testing and after all Asus’ RTX 3090 ROG Strix OC for the all-important GPU aspect of issues. For storage, we’re utilizing three PCIe 4.0 NVMe SSDs to maintain all of our video games – a 4TB Kingston KC3000, a 1TB PNY XLR8 CS3140 and a 1TB Crucial P5 Plus. Our rig was accomplished with a 1000W Corsair RM1000x power supply.

Elsewhere, we used an Asus ROG Crosshair 8 Hero for Ryzen 5000 testing, an Asus ROG Maximus Z590 Hero for 11th-gen Intel testing and an Asus ROG Z690 Maximus Hero for 12th-gen testing; all of those are high-end boards for his or her respective platforms. DDR4 motherboards used G.Skill 3600MT/s CL16 memory, the sweetspot for DDR4.

Before we get into the gaming benchmarks that make up pages two to 5, let’s whet our urge for food with some fast and soiled content material creation benchmarks: a Cinebench R20 3D render and a Handbrake video transcode.

Ryzen 5 5600X 601 4502 31.75fps 14.43fps 160W

As with the previous two Ryzen generations, we do get a pleasant efficiency uplift in productiveness that additionally spells out the most positive aspects we may anticipate to see in gaming. There’s a wholesome 25 p.c bounce in single-core speeds from the 5600X to the 7600X, as measured by Cinebench R20, and we see an analogous margin at the top-end too. Impressively, that increase permits the 7900X to outperform the 5950X in the multi-threaded Cinebench take a look at regardless of having 4 fewer cores and eight fewer threads; the 7950X ought to be an absolute titan. Moving over to the Handbrake transcode outcomes, and the 7900X is 13 p.c sooner than the 5950X when it comes to H.264 encoding and only a tad shy of that for H.265. The 7600X, for its half, outperforms the 5800X and 5800X3D with a mean transcode framerate of 20fps, in contrast to ~19 for the last-gen Ryzen 7 components.

Power utilization, measured at the wall for a fast comparability, is elevated for Ryzen 7000 in contrast to its predecessor – however it’s fairly modest, reality be informed. The new 6900X + X670E system drew 288W at its most, in contrast to 237W for the 5950X + X570 – a 21 p.c enhance that is kind of in-line with the elevated speeds we’re getting right here. It’ll be attention-grabbing to see whether or not mammoth coolers and extra energy unlock any significant efficiency positive aspects; on Ryzen 5000 the chip appeared to provide full utilisation out of the field however a shift to a brand new socket, increased energy targets and so on may imply there’s some overclocking headroom to uncover.

With these out of the means, let’s transfer onto the enjoyable stuff: testing how the 7600X and 7900X carry out in a spread of video games. Click the fast hyperlinks beneath to transfer onto the titles you are most interested by, or hit the ‘subsequent web page’ button to take all of it in!
