AMD Releases $99 Budget Processors and Revolutionary Ryzen 7 5800X3D with 96MB Cache

AMD has introduced six new CPUs in the 4000 and 5000 series, including those for the budget market starting at $99. All these chips will be on sale starting April 4, 2022. The list of processors and recommended prices is under the cut.

Here's what AMD's desktop processor lineup will now look like, sorted by recommended price (MSRP), starting with the lowest. New models are highlighted in bold.

AMD introduced them at the end of 2020, and there was nothing cheaper than $300 at all.

If you wanted to find something more modest, then the best option was processors like the Ryzen 3600, 3300X and 3100. But these models were in terrible short supply for many months, they were difficult to find, and you had to overpay. It got to the point that a competitor in the face of Intel pulled up with its 12th generation processors in the sub-$200 segment, such as the Core i3-12100 and Core i5-12400.

Now AMD is taking back the lead in this market. True, in order to reduce costs, the company has simplified budget chips as much as possible: they are designed on an older Zen 2 core and are equipped with a small cache: only from 6 to 11 MB. The Ryzen 4100 and 4500 are the first processors in the 4000 series without integrated graphics. According to some analysts, AMD's return to the ultra-budget market is probably due to the actions of a competitor.

The six new processors are distributed between $99 and $299 and should be a great option for building new budget machines or upgrading old ones. By the way, there is one more good news about the upgrade - they can be included in old motherboards with X370, B350 and A320 chipsets of the 2017 model.

New processors are released for the same socket AM4. But initially it was assumed that the Ryzen 5000 would only be compatible with 500-series motherboards, as shown by the following slide from the official presentation:

When this news was taken very badly, AMD quickly bounced back and promised that Ryzen 4000 support would continue on the B450 and X470 motherboards. And now there is some nice information: after updating the BIOS to version AGESA, old motherboards will be able to have all new processors, including both budget and the most expensive ones.

It is important to understand that the BIOS update on some motherboards adds support for Zen 3, but removes support for older pre-Ryzen Athlon processors. For example, see ASRock X370 Pro4 manual. Apparently, 16 MB BIOS memory chips are no longer enough to store the firmware of absolutely all AM4 processors.

It should be noted that older motherboards do not support all the functionality of new processors. For example, they do not support the latest versions of the USB protocol and the PCI Express 4.0 bus for modern GPUs and SSDs, so peripherals will not be able to use their maximum capabilities.

In addition, extreme CPU clock speed settings can be difficult on older boards, as newer boards have implemented new voltage regulator modules (VRMs) for this purpose, and the power lines are more optimized for power-hungry processors with a large number of cores.

On the other hand, 4- or 6-core chips of the new generation will fit perfectly into old motherboards, at least in terms of power.

Ryzen 7 5800X3D

In addition to six new models in the 4000 and 5000 lines, AMD announced the Ryzen 7 5800X3D, the first processor to feature 3D V-Cache stacking technology.

As you might expect, the Ryzen 7 5800X3D stands out among all AMD processors with a huge amount of L3 cache: here it is 96 MB. Previously, in the top AMD desktop processors, the cache size did not exceed 64 MB.

Other specs are to be expected: 8 cores, 15 threads, 3.4/4.5 GHz clock speed, 105W TDP.

Release date announced: April 20, 2022 and MSRP: $449.3D V-Cache is an innovative technology for layering L3 cache on TSMC's pipeline, which allows you to increase its volume by several times in the same area. For the first time, AMD has used 3D V-Cache in the next generation EPIC Milan-X server processors. For example, in the past, each chiplet with 8 cores contained 32 MB of L3 cache, with an area of ​​6 × 6 mm. Now another 64 MB cache layer will be applied on top of it, bringing the total volume to 96 MB per chiplet. For eight chiplets (64 cores) comes out 768 MB of cache, that is, 1.5 GB of L3 processor cache in standard two-processor servers.

Gradually, this technology will be brought to Ryzen desktop processors.

Other manufacturers (except TSMC) have similar technical inventions for multilayer chips.
