The second generation codenamed Cascade Lake is much better than the first generation Xeon Scalable processor in the Skylake-SP architecture, although it is still 28 cores and 56 threads (single die version, dual die package is 56 cores), AI performance has 30 times improvement, and other aspects have also improved significantly.
Today, Intel can't afford the performance test data of the second-generation Xeon scalable processor. Because it is a data center-oriented product, the running test and application are very different from the desktop version processor. Intel's understanding of performance improvement is also followed. What the players think is different, you can refer to how Intel considers this type of application.
The second generation Xeon Scalable Processor Family SKU is shown above. The Bronze 4200 series, the Gold 5200 series, the Gold 6200 series, and the Platinum 8200 series basically correspond to the current first generation. The first number represents product positioning, and the second The number "2" represents the second generation, and the suffixes N, Y, etc. are optimized for different applications.
It is worth noting that the second generation Xeon scalable processor has more than the strong platinum 9200 series, the flagship 9282 has come to the 56 core 112 thread through the two-chip package, but the main frequency has been increased to 2.6-3.8GHz, three levels The cache has also doubled to 77MB, the UPI bus has been increased to four, and the memory support has come to the twelve-channel DDR4-2933 with a maximum capacity of 1.5TB (standard version) and a thermal design power consumption of up to 400W.
At the same time there are 48 core 96 thread platinum 9242, the main frequency is 2.3-3.8GHz, the third level cache is 71.5MB, the bus and memory are the same as above, the thermal design power consumption is 350W.
32 core 64 thread platinum 9222/9221, the highest acceleration is 3.7GHz, the third level cache is still 71.5MB, the thermal design power consumption is 250W.
At the same time, note that the Platinum 9200 series is not an LGA independent package, but has been changed to a BGA integrated package, which is directly available to OEMs and will not be sold separately.
In terms of architecture, the Cascade Lake second-generation Xeon scalable processor is not much different than the current Skylake, mainly to improve the frequency and cache capacity, increase the DL Boost acceleration command, Speed Slect, AoTeng persistent memory, RDT optimization. With the support of new technologies, it has fixed bugs such as fuses and ghosts, and improved customization flexibility for different applications.
Performance, the second generation Xeon scalable processor has significantly improved compared to the current Xeon scalable processor, if you use the 56 core 112 thread platinum 9200 series to compare the 28 core 56 thread of the previous generation flagship platinum 8180, almost every The performance of the item is doubled, and the performance of AI image recognition is 3.5 times that of the existing product.
Of course, if you don't cross-border comparison, the same number of platinum 8200 series will still have a significant performance improvement compared with the current 8100 series. The same 28-core, platinum 8280 will increase by 6%, and increase by 120%. As for the gold series, because the Intel upgrade does not increase the price, more cores have improved the performance of the gold series by an average of 33%, and this increase is still very obvious.
Compared with its own products, Intel also wants to compare the products of the next friends. The choice is AMD's current strongest EPYC 7601 32-core 64-thread processor, from memory bandwidth, integers, floating point to database, JAVA and other performance tests, 56 The performance of the nuclear Platinum 9200 series is 40% higher than that of ECYC, and the number is multiplied.
Of course, the most disparity is of course the AI performance. The Platinum 9200 series is more than 25 times that of the EYPC 7601. Although this comparison is not acceptable to AMD, EMYC does not support AI acceleration. In this part of the application, it will indeed be a big score.
Not counting the platinum 9200 series of 56 core glue package, the platinum 8200 series with up to 28 cores and 56 threads still has advantages over AMD's 32-core EPYC. In addition to the memory bandwidth is not as good as the latter, other performances still lead the core number more. AMD processors, AI performance is still 16 times the latter.
Since the last generation, Intel has added the "extensible" name to the Xeon family of processors, emphasizing the parallel performance of the processor. On the second-generation Xeon-scalable processor, the dual-channel performance is 1.98x compared to the single-channel, which is almost doubled in proportion, and the performance of the 4-way system is also 3.88x, which is similar to the crossfire of the graphics card. SLI, the greater the parallel performance data, the better the benefits.
Not only is performance significantly improved, Intel also emphasizes the lower TCO cost of the second-generation Xeon scalable processors. They compared the Xeon processors five years ago, and the tests show the performance of the latest second-generation Xeon scalable processors. It can achieve 3.5 times the system five years ago, while saving 59% of the TCO cost, because the system that originally required 25 sets of Xeon processors is now only 6 sets, the performance is similar, and the cost is lower.
As for why the system was compared 5 years ago, the executives of the Intel R&D Center explained that the data center market is different from the consumer market. The 4-5 year is a normal upgrade cycle. Compared with the system five years ago, the customer is convenient to select a new generation of Xeon. The advantage is that almost no customer is upgrading the first generation of Xeon scalable processors and then upgrading the second generation Xeon scalable processors, all of which are upgraded after several years.
It should be noted that Intel also introduced a variety of combinations during the period, including the second-generation Xeon scalable processor with its own arrogant memory, hard disk and other configurations, when the performance improvement is more than a simple processor. As shown above, with the Intel data center hard drive, 100Gbps 800 series network card and other family barrel products, Intel second generation Xeon scalable processorWindowsThe performance under the Sever 2019 system is almost 26.8 times that of the system four years ago.
Of course, if you switch to AI, you don't have to compare the system 4-5 years ago. Compared with the generation of Xeon's scalable processor in 2017, the performance will be greatly improved. The performance of the 56-core Xeon Platinum 9282 processor will be able to improve. Up to 30 times that of Skylake, this performance is not a toothpaste.
