AMD, a famous technology giant, held a press conference at the Taipei Computer Show on May 27. The two blockbuster products in this conference are Navi series graphics cards and ZEN2 architecture CPUs. Of course, AMD still has a hand in releasing all models. More new series GPUs will be released on E3 this year.
According to the order of release of AMD, the first Navi graphics card is the Redeon RX 5700, which uses a new RDNA architecture, with the performance of each core increased by 25% and the performance of each watt increased by 50%. This is also the first AMD graphics card to use GDDR6 memory.
AMD didn't disclose any more information, but only showed the comparison with the high-end model Geforce RTX 2070 of competitor Nvidia at the press conference. In the show, the RX5700 was 10% faster than the RTX 2070. More information about Navi series graphics cards will not be released until this year's E3 exhibition.
The next step is the third generation of the Sharp Dragon, which is still expected to adopt ZEN 2 architecture.
First of all, Suma (AMD CEO) came up with a PPT, and explained that the performance of the third-generation IPC of the Reelung with ZEN 2 architecture was improved by 15%, the cache was doubled, the floating point computing performance was doubled, and the 7nm process technology was used throughout the line, with lower memory latency. The third generation of Sharp Dragon still uses the AM4 platform, which means that you can use the new Sharp Dragon 3 on the old AM4 platforms such as B350, X370, B450 and X470.
The first one is RYZEN 7 3700X, which adopts an 8-core 16 thread design. The default frequency is 3.6GHz, the Boost frequency is 4.4GHz, the L2 cache is 4MB, the L3 cache is 32MB, and PCIe 4.0 x16 channels, TDP 65W。
Compared with the previous generation R7 2700X, the single core performance of the R7 3700X is improved by 15%, and the multi-core performance is improved by 18%. The TDP is reduced from 105W to 65W.
The on-site and competitive intel i7-9700K compared the scores of Cinebench R20. The single thread is basically the same. Multi thread leads by 28%. You should know that the 9700K single core maximum Remax frequency is 5.1GHz, while the 3700X single core Remax frequency is only 4.4GHz. Thanks to the improvement of IPC performance, the 3700X with lower frequency leveled the 9700K with high frequency. I really have to admire AMD. Now the performance of RYZEN single core is not inferior to that of toothpaste factory i7, and the multi-core is directly rolled.
Next is RYZEN 7 3800X, which also uses an 8-core 16 thread design. The default frequency is 3.9GHz, and the Boost frequency is 4.5GHz. The L2 cache and L3 cache are consistent with the 3700X, which are 4MB and 32MB respectively. PCIe 4.0 x16 channels, TDP 105W。
The R7 3800X is designed for games. CSGO has achieved a double-digit increase. Other E-sports games have also improved to varying degrees.
I ran a 3D Mark PCIe test on site, I/O terrorist data throughput of PCIe 4.0.
Finally, RYZEN 9 3900X, 12 core 24 thread design, default frequency 3.8GHz, Boost frequency 4.6Ghz, L2 cache 6MB, L3 cache 64MB, PCIe 4.0 x16 channels, TDP 105W。
The final R9 3900X can be said to be a blockbuster. The i9-9920X on the X299 platform with 12 cores and 24 threads scored better than the Cinebench R20. In the end, the total rendering time of the R9 3900X was 18% faster than that of the i9-9920X. The speed of single thread is 14% faster and that of multi thread is 6% faster, which is amazing. You should know that the box price of i9-9920X in JD is close to 10000 yuan, and the X299 motherboard is more expensive than the AM4 motherboard. AMD's use of the entry-level AM4 platform to compete with Intel's high-end X299 platform is very impressive.
AMD secretly released RYZEN 5 3600 and RYZEN 5 3600X on the official website, both of which use six core 12 threads. The former has a default frequency of 3.6GHz, the Boost frequency of 4.2GHz, the latter has a default frequency of 3.8GHz, the Boost frequency of 4.4GHz. The cache also uses 3MB L2 cache, 32MB L3 cache, PCIe 4.0 x16 channels, the former TDP 65W, and the latter 95W. The performance of R7 and R9 is also very fragrant.
Finally, the following prices are announced:
RYZEN 9 3900X sells for 499 US dollars, equivalent to RMB 3400;
RYZEN 7 3800X sells for 399 US dollars, equivalent to RMB 2748;
RYZEN 7 3700X sells for 329 dollars, equivalent to 2268 yuan;
RYZEN 5 3600X sells for 249 dollars, equivalent to 1700 yuan;
The price of RYZEN 5 3600 is US $199, equivalent to RMB 1370.
The Sharp Dragon 3 will be launched on July 7. At present, the domestic price has not been announced. With reference to the American price, it can be said that the cost performance ratio is very high, especially the peak of R9 3800X and AM4.
Fan A's mood can only be described in one sentence, “AMD，yes”， This ZEN 2 really brought a lot of surprises. It not only improved the memory latency of the first generation of Reelon, but also improved the IPC performance by 15%. The floating point performance doubled, the number of caches doubled, and the whole line supported PCIe 4.0 x16. The most important thing is that there is no toothpaste squeezing. I am used to the vest CPU of the toothpaste factory every year, and there is no power to upgrade the hardware. While the Sharp Dragon 3 of AMD can be said to be very attractive, but after watching the press conference, the editor has wanted to upgrade the R7 2700 to R9 3900X. Fortunately, he took a look at the wallet and restrained his bold ideas in time.
