Intel recently announced that the fourth generation Xeon scalable processor code named sapphire rapids has begun to ship the first batch of models to customers. Sapphire rapids adopts Intel 7 technology and golden Cove architecture, which are of the same origin as the 12th generation core. Of course, they are all big cores. They also adopt a new multi-core integrated package, which integrates up to four small chips. They can also integrate hbm2e high bandwidth memory. The package is replaced with a new lga4677, which supports eight channel ddr5, PCIe 5.0, CXL 1.1 and so on.
According to the latest exposure, sapphire rapids Xeon has four levels of power consumption according to TDP thermal design: platinum 300-350w, gold 270-300w, silver 205-250w and bronze 150-185w**
Combing the known engineering samples, we can know that there are at least six core, cache and power consumption configurations:
- 24 cores, 48 threads, 45.0mb L3 cache, 225W TDP
- 28 cores, 56 threads, 52.5mb L3 cache, 250W TDP
- 40 core, 80 threads, 75.0mb L3 cache, 300W TDP
- 44 core 88 threads, 82.5mb L3 cache, 270W TDP
- 48 cores, 96 threads, 90.0mb L3 cache, 350W TDP
- 56 core 112 threads, 105.0mb L3 cache, 350W TDP
As for why the TDP of 44 core is lower than that of 40 core, it is unknown for the time being. It may be the difference of acceleration frequency.
At present, the basic frequencies of samples are very low, such as 24 core 1.5GHz, 28 core 1.3GHz, 40 core 1.3GHz, 44 core 1.4GHz, 48 core 1.3GHz and 56 core 1.6GHz , and the acceleration frequency is unknown.
There is also a gold medal model starting at 2.2GHz, which has the highest known frequency, but the number of cores is unknown.
In addition, the thermal design power consumption of TDP above is Pl1, while the higher pl2 will generally exceed 400W, and the highest is even about 700W**
