One of the most important present issues for any potential purchaser of a graphics card is having the ability to discover the mannequin they’re searching for in shops and that it’s at an affordable worth. The cause for this is understood to everybody and has to do with cryptocurrency mining. However, a GPU that’s good for gaming doesn’t have to be good at mining cryptocurrencies. Which is the case with AMD’s RX 6700 XT. Will it’s saved from the clutches of the miners? Let’s see the rationale and the causes of it.
AMD RX 6700 XT worse on Ethereum than RX 5700 XT
Through a weblog devoted to cryptocurrency mining on VideoCardz we now have discovered that within the face of mining the cryptocurrency Ethereum, the RX 6700 XT has worse performance than the RX 5700 XT. Which is stunning because the transition from RDNA to RDNA 2 we must always anticipate a a lot greater performance.
According to mentioned weblog, the RX 6700 XT has a hash price of 43.5 MH / s, which is a a lot decrease determine than the 54.75 MH / s of the RX 5700 XT. Which is stunning when you think about not solely the advance in structure but in addition the upper clock velocity of the brand new AMD graphics card.
This, which in precept is dangerous information for miners, interprets into excellent news for many who need to replace their PC with a brand new graphics card, both to play video video games or for extra skilled duties akin to scene modeling and rendering. on an expert stage as a hobbyist.
Bandwidth, an vital issue when mining Ethereum
The cause the AMD RX 5700 XT is superior to the RX 6700 XT in mining is as a result of of the bandwidth of the VRAM reminiscence. We can not overlook that whereas the AMD RX 5700 XT makes use of a 256-bit GDDR6 bus, within the case of the RX 6700 XT its bus is 25% narrower with solely 192 bits below the identical sort of reminiscence.
That is why on the stage of mining Ethereum probably the most highly effective graphics card by AMD isn’t an RDNA exactly, however the nearly unpublished Radeon VII that with its bus of greater than 1 TB / s of bandwidth through HBM2 reminiscence exceeds far in bandwidth from VRAM to the RX 6900 XT.
So the benefit isn’t in phrases of structure however slightly reminiscence bandwidth. Although this leads us to the query: what concerning the Infinity Cache? Theoretically, it offers RDNA 2-based GPUs a bonus in bandwidth and particularly in consumption, which in principle must be helpful for mining.
The Infinity Cache is totally ineffective to miners, as it’s a Victim Cache, it doesn’t take part within the VRAM information seize course of, the place the method is identical on each the CPU and GPU. The job of the Infinity Cache is to undertake the cache traces and due to this fact the discarded information from the second-level cache of the GPU itself, in order that when trying to find them the GPU doesn’t have to entry the GDDR6. It permits entry utilizing much less energy and thereby rising the clock velocity margin.
So not solely does the RX 6700 XT not have any benefit when it comes to mining Ethereum, however the identical can be mentioned for the remaining of the AMD RX 6000 vary.
