This year, Intel will release Sapphire Rapids server processors based on the 10nm process technology and the Golden Cove architecture.
We have known for a long time that these CPUs will be multi-chip. More specifically, they will contain four chips, which Intel itself calls tiles. Each tile will have 15 cores, that is, in total we are talking about 60 cores. But all the data indicate that Intel will not release 60-core models, but will limit itself to 56 cores.
Today, technical details about the internal structure of these CPUs appeared on the Web.
So, each CPU tile is actually a separate full-fledged processor with an integrated northbridge, memory and PCIe interfaces, as well as other I / O interfaces. There are also five EMIB bridges allocated to each tile.
Within each tile, the layer layout is similar to several previous generations of Intel enterprise processors. Intel uses the Mesh connection and places various IP blocks on the mesh, connecting them into a ring bus network. Each tile contains 15 CPU cores, each with 2 MB of dedicated L2 cache and 1.875 MB of L3 cache chunk, which provides a total of 28.125 MB of L3 cache. It is shared by all 60 cores of the kernel. The total L3 cache for the CPU is 112.5 MB. Each tile also has a memory controller unit with 128-bit (160-bit including ECC) DDR5 memory.
The PCIe/CXL interface for Sapphire Rapids is huge. Each tile is equipped with a PCIe 5.0 and CXL 1.1 root complex with 32 lanes, which equates to 128 PCI-Express Gen 5 or CXL 1.1 lanes.
AMD video cards have become dramatically faster by up to 17%, and possibly more. The test of the new driver showed that there really is an increase
AMD recently promised that its new graphics driver will bring gaming performance up to 24%. This driver is already available and we have test results.
Unfortunately, the source did not test the games Crysis Remastered and Total War Saga: Troy, where AMD promised 24% and 17% growth, respectively. But even without them, the situation is generally clear.
As you can see, on average for 50 games, the increase was 2-3% depending on the resolution, which is completely imperceptible during the game. But still it is more correct to look at the results in specific games.
And there really is something to appreciate. If we talk about Full HD, then in Watch Dogs: Legion the increase was 12%, and this is the maximum figure. At the same time, in 2K resolution in the same game, the increase was already 17%.
Also, a noticeable increase was observed in Death Stranding, Apex Legends, The Witcher 3, Forza 5 and a number of other projects. If we compare the results with AMD’s promises, then in the same Apex Legends the company promised a 5% increase, but in fact we have from 6% to 9% depending on the resolution, that is, the result is even better. So, perhaps, in the same Crysis Remastered, the growth will be even more than the promised 24%.
Separately, it is worth highlighting Godfall, where the new driver, on the contrary, leads to a decrease in performance by 2-7%.
No, AMD will not be the first to offer a dual-chip chipset to the market. Asus X670 Prime motherboard schematic showing two separate chips
It looks like all the rumors about AMD’s dual-chip chipsets were wrong after all.
Recall that in recent days there have been reports that the X670 will be a chipset consisting of two chipsets on one substrate. But, apparently, a broken phone or a bad translation of some source data from some Asian language worked.
In any case, as you can see on the diagram of the Asus X670 Prime mainboard, the chipset will indeed have two chips, but they will be completely separate. This is similar to the northbridge/southbridge circuit that was used extensively in the past, but in this case, according to the available data, the chips are exactly the same. The chipset chip is codenamed Promontory and is an ASMedia development.
Judging by the diagram, one of the microcircuits will be located directly under the video card slot, and for now we can only guess if this will lead to excessive heating.
Recall that AMD will present new chipsets at Computex 2022 the other day.
This is what the first motherboard for Ryzen 7000 processors looks like. ASRock X670E Taichi lit up on the Web
In a few days, AMD will introduce the X670E, X670 and B650 chipsets for AM5 platform motherboards designed to work with Ryzen 7000 processors. But today we can get our first look at such a board.
ASRock itself showed the X670E Taichi on video, however, the video has already been deleted. As the name implies, the board is based on the top X670E chipset, but technically it will not differ from the X670. Recall that both chipsets will be dual-chip, that is, they will consist of two identical chipsets on one substrate.
So far, we can say something about the board itself only by looking at the image. You can see two PCIe slots, four DDR slots, a processor socket, and what appears to be a passively cooled chipset. This gives hope that it will not heat up too much.
