The Ryzen 9 7950X3D and 13900K: AMD’s 8th-Generation High Performance CPUs in Synthetics and Rendering
We are going to see how it will affect productivity and rendering apps, as well as the usual PC gaming performance improvements at the highest level of AMD’s consumer offerings, due to the choice ofExtending 3D V-Cache technology to its Ryzen 9 chips.
Over on the synthetics benchmarks and productivity side, Intel is still largely ahead. The 7950X3D loses out on PugetBench’s Photoshop test but manages to close the gap on the Premiere Pro side. The 7950X3D is behind both Intels latest Core i9 chips in Geekbench 5 and Cinebench R23. It falls behind in the Time Spy test and 3DMark test.
Intel has a larger power budget and is drawing in gaming tests to try to edge ahead of the competition. AMD upped its first flagship Zen 4 chips to a 170-watt TDP, but it has dropped this Ryzen 9 7950X3D to a TDP of 120 watts. The Core i9-13900K has a base power of 125 watt and has been bumped up to 150 watt by Intel. At max turbo power, both of Intel’s latest chips hit slightly above 250 watts and can go way beyond this if a motherboard is set to unlimited power. The difference can be as much as more than 200 watts between the 7950X3D and 13900KS on identical multithread loads. Digital Foundry also found that the 7950X3D draws significantly less power than Intel’s Core i9-13900K.
This may seem like an underdog compared to Intel’s top 13th-Gen chips, which have 24 cores — Intel has claimed that its Core i9-13980HX is the “world’s fastest mobile processor”. The chip has only eight performance and 16 efficiency cores, while the other 16 of the Ryzen’s will be full speed ahead. This is essentially two full eight-core chips stuffed into one.
It’s hard to know how exactly these two laptops will perform relative to one another and whether either of them will burn a hole in your table until we’ve gotten to try these units out for ourselves. The Ryzen 9 7955HX is in a very competitive position. AMD is claiming that these chips will deliver a 78 percent increase in Cinebench performance over last year’s Ryzen 6900HX. With the specs I’m seeing here, that would not surprise me.
The Zen 3+ 7035 series is listed in the slideshow as a selling point, because of its amazing battery life. I will take that the Zen 3 7030 series has proven great battery life.
I have been testing out a lot of different computers, includingAMD’s 7950X3D, G.Skill’sDDR5 6000 ram, and nVidia’s R4090 card. The AM5 has one slot for the PCIe 6.0 M.2 and three for the PCIe 4.0 M2. There is enough room for the latest storage.
The Verge doesn’t review processor in the traditional sense, so we don’t own dedicated hardware testing rigs or multiple units to offer all of the benchmarks and comparisons you’d typically find in CPU reviews. We’re going to recommend Eurogamer’s Digital Foundry, Tom’s Hardware, and PC World for those.
Both AMD and Intel have also been maximizing thermal headroom lately. During our previous review, the Core i9-13900K hit 100C and the 7950X ran at 95C. I noticed the 13900KS hitting 101C in a multithread load, while the 7950X3D managed 86C during the same test. The Corsair H 150 is the same as both of the CPUs. The top of the range cooler.
Existing AM4 coolers should work just fine, and much like the 7950, I was able to use Corsair’s H150 Elite LCD without any changes required. You’ll need to check with your cooler manufacturer to make sure that existing AM4 models can easily be used with these new AM5 motherboards.
A note on memory training on Ryzen 9 7900X and new vista meg X670E-c resummation
I noticed some early issues with the DDR5 memory training process during my Ryzen 9 7900X review, with an additional boot time of around 30 seconds. I have been testing an Intel system and it is still taking longer to start up than the NewBIOS updates address this.
I’m pleased to report that the sleep mode issues I also experienced during the Ryzen 9 7900X review have been fixed. The latest updates to themsi Meg X670E Ace can now resume from sleep.
