10 Comments. Intel’s 28-core/56-thread Xeon 8280, for comparison, is $10,009. 7742 vs 8280 specifications comparison The graphs below demonstrate the difference between Xeon 8280 and AMD 7742 most important characteristics. The EPYC 7742 allegedly built the Linux kernel up to 53.86% faster than a Xeon Platinum 8280 and up to 5.64% faster than dual Xeon Platinum 8280s. This difference in scaling means that a pair of dual Xeon 8280’s nearly match a pair of Epyc 7742’s, even though one Epyc 7742 is significantly faster than one Xeon Platinum 8280. The downside? That is absolutely insane and I am willing to wager whatever TCO (total cost of ownership) model you use, this is going to be a significant factor.For latest tech news in your inbox, once a day!Let's start with the SpecIntRate_2017_rate_base figures. 25 Comments. The EPYC 7642 2P delivered roughly 1.16x the performance of the dual Xeon Platinum 8280 while running just half the price of dual 8280s. Throw in the recent security issues with Intel chips and AMD starts to look really good.Even if they don't care about cost vs performance, Rome is still the strongest CPU overall. vs Xeon 8280. vs Xeon 9282. vs i9-9900K.
A benchmark of an EPYC 7742 and two xeon 8280s (56 cores 112 threads (clock speed minimum: 2.7 GHz. If you translate this to a performance per dollar figure, you are looking at a 5.2x lead for the AMD part! This is because you've validated your software on a specific architecture, have all your vendors lined up, your tools for managing your servers set up, etc...But waddya know, the EPYC systems were slower because they were running more virtual machines:When people know that EPYC 7 nm+, 5 nm, 3nm will be on time, cloud ISP will seriously look this solution. In HEVC, the performance figures change. This would allow all cores to share the entirety of the L3 cache available on the die rather than each CCX having its smaller and separate cache shared among the cores. So after adding the relevant and interesting tests to the Phoronix Test Suite that weren't in there already, I was curious to check on the Xeon Cascade Lake vs. EPYC Rome performance from this sub-set of tests recommended by Intel for use in the public procurement of systems. This is roughly twice the performance of the Intel counterpart and if you think this is impressive, wait till you consider the pricing implications.We see a somewhat similar situation in the GROMACS ARCHERII benchmark where the cascade lake 8280 setup achieves 4.498 nanoseconds per day while the EPYC 7742 scores 6.329 nanoseconds per day. A single 7742 is considerably sooner than the Xeon Platinum 8280 and the 7742 is greater than twice as quick because the 7601. 2nd Gen AMD EPYC : A Quick Primer. Right here, Intel and AMD are at parity total, however the 7742 is a large uplift over and above the Epyc 7601. They seem to thing of Intel the way that they used to think of IBM, "There can be only one, Highlander!"But if the benefit becomes large enough you'll bother with the trouble to do that. The "Number of cores / threads" graph shows the number of cores (darker area). those are even more expensive than these ones!AMD has shown that unlike Zen 2 which has 16 MB of L3 cache per CCX within a CCD, Zen 3 would feature a shared cache (32 MB+) for each die. Where for most consumers its #1 or #2This is in addition to Intel commissioning a whitepaper earlier this year comparing a Xeon Platinum 8160 to an EPYC 7601, where they happily claimed that the Xeon chip was faster in a mixed cloud workload.Why it doesn't surprise me Intel recommends the few benchmarks where their 28-core part is good enough to compete with AMD's 48-core. This is one of the more well-known performance estimates for high-performance computing and is a category that has historically been dominated by Intel. Intel’s Next-Gen 10nm Ice Lake-SP Xeon 28 Core / 56 Thread CPU Benchmarked Against AMD’s 7nm EPYC Rome 7742 64 Core CPU Blog / By Er Abhishek Kumar Agrahari The latest benchmarks of Intel’s next-generation Ice Lake-SP Xeon CPU server family have leaked out and they show some interesting results when compared to AMD’s current generation 3rd Gen EPYC Rome CPUs. Written by Michael Larabel in Hardware on 27 February 2020 at 01:57 PM EST. AMD also confirmed that they are currently sampling the first Milan CPUs which is fantastic news for customers awaiting the chips in 2020. So here are those benchmarks for some weekend benchmark results.Tested were the EPYC 7742, EPYC 7642, Xeon Platinum 8280, and the EPYC 7601 for previous-generation comparison -- all tests this round done in the dual socket configuration. The EPYC 7742 2P delivered 1.25x the performance at just about three quarters the price of the top-tier non-AP Cascade Lake processors.
This time around for some curiosity over the weekend is a look at the EPYC 7642 and EPYC 7742 up against the Xeon Platinum 8280 …
