first isEPYC7663P, which is the single-channel version of EPYC7663, the specifications are almost identical, with 56 cores and 112 threads, 2.0-3.5GHz frequency, 256MB L3 cache, and 240W thermal design power consumption. The only difference is that the adjustable range has been expanded from 225-240W to 225-280W.
The most important thing is that the wholesale price of 1,000 pieces has dropped from US$6,366 to US$3,139 (approximately RMB 22,800), which is half the price.
followed byEPYC7643P, which is the single-channel version of EPYC7643, also has 48 cores and 96 threads, 2.3-3.6GHz frequency, 256MB L3 cache, 225WTDP (range 225-240W),The price has dropped from US$4,995 to US$2,722 (approximately RMB 19,800), which is nearly half the price.
EPYC7303/7303PBoth have 16 cores and 32 threads like the existing EPYC7313/7313P, but the frequency is reduced from 3.0-3.7GHz to 2.4-3.4GHz, the third-level cache is halved to 64MB, and the TDP155W is reduced to 130W (the adjustable range is reduced to 120-150W).
The prices have dropped from US$1,083 to US$913 respectively.604 US dollars (approximately RMB 7,310), 594 US dollars (approximately RMB 4,325).
EPYC7203/7203P is the lowest-end 8-core 16-thread model., frequency 2.8-3.4GHz, level 3 cache is only 64MB, TDP is only 120W (adjustable range 120-150W),The price is only 348 US dollars and 338 US dollars, which is approximately RMB 2,530 and 2,460 yuan.
In comparison, the EPYC72F3, which also has 8 cores but has a frequency of 3.7-4.1GHz and a L3 cache of 256MB, costs as much as $2,468.
The six new models all retain the specifications of 8-channel DDR4-3200 memory and 128 PCIe4.0 lanes., has the same excellent scalability.
