AMD details Radeon RX 400 series naming conventions, confirms RX 490
|
AMD has released the first graphics card of the Polaris family, the RX 480. You should also notice that this time AMD not only brought new architecture products, but also changed the naming method. We will see graphics cards such as RX 480, RX 470 and RX 460. AMD recently publicly explained the meaning of the new naming method. At the same time, AMD also implicitly confirmed that the RX 490 graphics card will have a memory bus width greater than 256bit and is designed for 4K, while the RX 480 is designed for 1440p resolution. AMD's new generation of graphics card naming method Specifically, Radeon is a graphics card brand and will continue to be retained. It will be divided into two series, RX and non-RX. The former mainly refers to graphics cards with floating point performance of more than 1.5TFLOPS and bandwidth of more than 100GB/s (to be determined). In popular games such as DOTA 2 and LOL, it can have 60FPS frames at 1080p. The performance of the Radeon 400 series is inferior. The first digit represents the product generation, and the current number is 4 - that is, the fourth generation after HD 7000/R200/R300. The number after 4 represents the product level (Tier). The RX series has 5 levels: 9, 8, 7, 6, and 5, and the non-RX series also has 3 levels: 6, 5, and 4. The meaning of each number is as follows: ?, representing a bit width greater than 256 bits, born for 4K?, 7, bit width 256 bits, born for 1440p?, 5, bit width 128 bits, for 1080p resolution (applicable to RX and non-RX series)?, bit width 64 bits, no mention of resolution, it is probably an entry-level card for starting the computer. It should be noted that the RX and non-RX series have repeated names 6 and 5, which means that in the future there will be RX 460/465, RX 450/455 and Radeon 460/465, 450/455 coexisting, which is easy to confuse people. The editor speculates very unkindly that the RX 46X/45X series may be the vest products of the previous generation. The last digit represents the revision, where 0 represents the first generation and 5 represents the second generation. Taking the currently announced RX 480 graphics card as an example, this name means that it is a mid-to-high-end graphics card in the Radeon RX 400 series, with a bit width of 256 bits, and is a first-generation product. AMD's announcement of the new name also hints at the existence of the RX 490 video memory, whose video memory bit width will be higher than 256 bits, mainly for 4K resolution, and there may be a second-generation RX 495 graphics card in the future. According to AMD's previous news, after Polaris, the Vega core will be used, and HBM 2 video memory will be used. The equivalent bandwidth of this video memory is at least 4096 bits, which is much higher than 256 bits, but it is not certain that all products in the Vega series will be equipped with HBM 2 video memory, so the RX 490 may still use 384-bit GDDR5 or GDDR5X, and 512-bit GPUs may no longer be used. As a winner of Toutiao's Qingyun Plan and Baijiahao's Bai+ Plan, the 2019 Baidu Digital Author of the Year, the Baijiahao's Most Popular Author in the Technology Field, the 2019 Sogou Technology and Culture Author, and the 2021 Baijiahao Quarterly Influential Creator, he has won many awards, including the 2013 Sohu Best Industry Media Person, the 2015 China New Media Entrepreneurship Competition Beijing Third Place, the 2015 Guangmang Experience Award, the 2015 China New Media Entrepreneurship Competition Finals Third Place, and the 2018 Baidu Dynamic Annual Powerful Celebrity. |
