AMD has released a graphics card Polaris family first RX 480, we should also note the AMD this time not only brought a new product architecture, naming has changed, we will see the RX 480, RX 470 and RX 460, etc. graphics card. For the new naming scheme, AMD recently publicly explain its meaning, while AMD also implicitly confirmed the RX 490 graphics card, the memory interface will be greater than 256bit, for 4K born, and RX 480 is for 1440p resolution .
AMD next-generation graphics naming
Specifically, Radeon graphics card brand will remain, after the RX will be divided into two series and non-RX, the former mainly refers to the floating point performance 1.5TFLOPS more bandwidth greater than 100GB / s (to be determined), the popular games such as DOTA 2, LOL in graphics frames have 60FPS at 1080p under, Radeon 400 series performance will Some times.
The first number represents the algebraic product, now is 4-- is the fourth generation of HD 7000 / R200 / R300 later.
4 after the figures represent the product level (Tier), RX series 9,8,7,6,5 five levels, non-6,5,4 RX series also has three levels, meaning each number represents the following:
2.9, representing more than bits wide 256bit, born for 4K
* 8,7, bits wide 256bit, born to 1440p
* 6,5, Width 128bit, for 1080p resolution (for non-RX and RX series)
· 4-bit wide 64bit, did not mention the resolution, it is estimated that an entry-level light machine card
Note that, RX and RX series named non-repetitive 6,5, which means I will have RX 460/465, RX 450/455 and Radeon 460/465, 450/455 exist, this is confusing ah, Xiao Bian very kind to guess RX 46X / 45X series might is the previous generation of products vest.
It is the last digit represents the version (revision), where 0 represents the first generation of digital, digital 5 represents the second generation.
In the current release over RX 480 graphics card, for example, this means that it is named Radeon RX 400 series of high-end graphics, Width 256bit, is the first generation product.
AMD announced the new name also implies the existence of memory RX 490, which will be higher than the memory interface 256bit, mainly for 4K resolution, follow-up may also have a second-generation RX 495 graphics card.
According to AMD before the news, after Polaris Vega is the core, and will spend HBM 2 memory, this memory is at least equivalent bandwidth 4096bit, far higher than 256bit, but are unsure of Vega series products are all equipped with HBM 2 memory, so RX 490 is still possible to use 384bit bit wide GDDR5 or GDDR5X, 512bit bit wide GPU probably may no longer engage.
