Ryzen 7 5800X3D: AMD's new top gaming CPU

V-Cache was previewed at Computex in 2021, and it works by stacking a cache die on top of the existing 7nm Zen 3 chiplet to significantly increase the amount of L3 cache. If we zoom into this rendered image of the 5800X3D, you can see the area in the middle where this extra silicon is layered on the existing CPU, with the CPU cores at the edges.

With V-Cache, the 5800X3D goes from 32MB of L3 cache, to a total of 96MB – the original 32MB on the Zen 3 chiplet plus 64MB of V-Cache. The rest of the CPU remains essentially identical to the 5800X – it’s an 8 core, 16 thread design, it’s an AM4 chip that works on 400 and 500 series motherboards, and it has a 105W TDP. However, clock speeds are slightly lower than the regular 5800X, the base has dropped from 3.8 to 3.4 GHz, and the boost from 4.7 to 4.5 GHz. I suspect this is a combination of needing to keep the extra cache within the same power envelope, and limitations on how fast you can clock the V-Cache component.

At this stage, AMD are only saying the 5800X3D will be available in the spring and no pricing has been announced. It’s also the only consumer V-Cache chip that will be released at that time. We asked AMD whether they’d be bringing it to more CPUs but they said this is the only one – for now.

 

 

AMD at CES 2022: Roadmap to Zen 4 and AM5, Ryzen gets V-Cache, Ryzen 6000 mobile, more

Let’s kick this off with a look at AMD’s desktop announcements and if you’re a CPU enthusiast then the big one for you will be the Ryzen...

 

Love the competition AMD is bringing these days!

The roadmap to Zen 4

Also on the CPU side, AMD teased upcoming products scheduled for release later this year.

Zen 4 will be coming to desktop platforms in the second half of 2022, using 5nm process technology. AMD confirmed the CPU has a different visual design as well, featuring what appears to be a larger heatspreader with different cutouts and quite an unusual design compared to the cleaner heatspreaders we’ve seen on Ryzen so far.

 

Alongside Zen 4 will be a new socket, unsurprisingly called socket AM5 which moves from a PGA to LGA layout, LGA 1718 to be specific. It will be compatible with existing AM4 CPU coolers, but provide substantial I/O improvements, including DDR5 and PCIe 5.0, giving AMD feature parity with Intel’s current line-up.

Hopefully by the time AM5 is released, DDR5 will be more available and more affordable (AMD gave no indication if DDR4 will be supported).

As both Zen 4 and AM5 are expected much later in 2022, details were light, but everything appears to be on track for a launch this year.

New Budget Radeon RX 6500 XT

Moving into desktop graphics, AMD announced the Radeon RX 6500 XT as a new mainstream option for gamers... if you can actually buy one, of course, which these days is not a given. This compact GPU features 16 compute units, 16 MB of infinity cache, and a 2.6 GHz game clock, so it’s essentially half of a Radeon RX 6600 XT. AMD didn’t reveal the memory subsystem specs, probably because it’s expected to be just 4GB of GDDR6 on a weak 64-bit bus.

Definitely interested to see how the 5800X3D plays out in real world testing. Primarily wondering about thermals and actual performance. Would happily ditch my 5600X for that and then call it good for many years if it pans out well and isn't priced outrageously. 

 

Though given Zen 3 pricing, I would be inclined to wait till Micro Center drops prices on them.
