Due to a giant step up in general VRAM clock velocity, the Nvidia GeForce RTX 5080 could have a complete reminiscence bandwidth that’s truly greater than the RTX 4090, regardless of having a a lot narrower reminiscence bus. That’s in accordance with a brand new leak that means the addition of GDDR7 to the RTX 5080 will massively enhance its reminiscence throughput.
As what’s anticipated to be Nvidia‘s second greatest graphics card choice when its new vary of gaming GPUs launches subsequent yr, the RTX 5080 stands a superb probability of outperforming the RTX 4090 anyway. This is able to match with the long-standing development of recent Nvidia GPUs the place the present era x080 card beats the earlier era x090 card, however we wouldn’t essentially have anticipated the RTX 5080 to outpace the RTX 4090 in the case of reminiscence bandwidth.
That’s as a result of the RTX 4090 makes use of a really huge 384-bit reminiscence bus, which suggests it actually has 384 connections from the GPU to the reminiscence, whereas the RTX 5080 is predicted to have a smaller 256-bit reminiscence bus. Nonetheless, a brand new leak hints that the RTX 5080 will probably be outfitted with 32Gbps GDDR7 VRAM, which is over 52% sooner than the 21Gbps GDDR6X VRAM used within the RTX 4090.
Because of this, the RTX 5080 would have a complete reminiscence bandwidth (VRAM velocity x reminiscence bus width / 8) of 1,024GB/s in comparison with 1,008GB/s for the RTX 4090. This totally pales compared to the anticipated RTX 5090 reminiscence bandwidth, nevertheless, as that card is believed to have a 512-bit bus with GDDR7 reminiscence working at 28Gbps, for a complete bandwidth of 1,792GB/s.
That is all in accordance with WCCFTech that cite “our sources” as offering particulars to the location of Nvidia’s upcoming opening keynote speech for CES 2025, the world’s largest tech commerce present going down in Las Vegas in early January 2025. Together with particulars of the RTX 5090 and RTX 5070, the claims embrace this intriguing element concerning the RTX 5080.
Finally, reminiscence bandwidth alone isn’t sufficient to find out general gaming efficiency. Too little and you’ll be assured a graphics card will underperform, however the general efficiency of the RTX 5080 will probably be an interaction of the variety of processing cores within the GPU, the velocity of the GPU and the velocity of the reminiscence.
You possibly can be taught extra about every part we all know to this point to do with the RTX 5080 in our Nvidia GeForce RTX 5080 information, however when you’re in search of a discount proper now, you possibly can take a look at our Amazon Prime Day offers web page for some graphics card reductions.
