Tonight, Intel, AMD, and NVIDIA will all announce new processors and graphics products at CES 2022.

Now, we've even learned some secrets about THE AMD Zen4 architecture in advance.

According to the exposure, the AMD Zen4 architecture will be manufactured using TSMC's 5nm process, and the corresponding products include the Ryzen™ 7000 Rapheal for desktop, the Ryzen™ 7000H/7000U Pheonix for notebooks, and the Xiaolong 7004 Genoa for data centers.

We heard before that the Zen5 architecture will use a large and small core configuration, of which the small core is Zen4D, but it seems that Zen4 will be on the size core in advance!

thereinto The large core is the full Zen4, also known as the "Priority Core", each Die (CCD) has 8, the small core is a residual version (LTDP) that reduces the power consumption of the thermal design, each Die is also 8, the total thermal design power consumption is 30W, an average of 3.75W each.

It is said that the Zen4's Ryzen™ 7000 series thermal design consumes up to 170W, so the average is 17.5W per large core.

In terms of caching,Each pair of size cores shares 1MB of L3 cache, for a total of 8MB, and all cores share 64MB of L3 cache, but it doesn't look like it's directly integrated, but is stacked extra in the form of v-Cache.

The upcoming Zen3 V-Cache version has a V-Cache stack cache, but it comes with a level 3 cache plus additional stacking.

Such a design,In the case of two Die (CCD) integrated packages, a single processor can easily achieve 32 cores and 128MB level 3 cache.

In other respects, Zen4 will be used insteadNew AM5 LGA1718 package interface backing Dual channel DDR5-5200 memory, 28 PCIe 5.0 channels, NVMe 4.0, USB4With the motherboard, it is expected to be X670 and B650.

The Zen4 Ryzen™ 7000 series is expected to be released as soon as the third quarter of next year, facing the Raptor Lake 13th Generation Core, which is an upgraded version of the 12th Generation Core, continuing the Intel 7 process, large and small core design.
