Due to an enormous step up in total VRAM clock pace, the Nvidia GeForce RTX 5080 could have a complete reminiscence bandwidth that’s truly increased than the RTX 4090, regardless of having a a lot narrower reminiscence bus. That’s in keeping with a brand new leak that implies 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 possibility when its new vary of gaming GPUs launches subsequent 12 months, the RTX 5080 stands a very good probability of outperforming the RTX 4090 anyway. This may match with the long-standing pattern of recent Nvidia GPUs the place the present technology x080 card beats the earlier technology x090 card, however we wouldn’t essentially have anticipated the RTX 5080 to outpace the RTX 4090 with regards to reminiscence bandwidth.
That’s as a result of the RTX 4090 makes use of a really vast 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. Nevertheless, a brand new leak hints that the RTX 5080 can 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 pace x reminiscence bus width / 8) of 1,024GB/s in comparison with 1,008GB/s for the RTX 4090. This completely 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 keeping 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 embody this intriguing element in regards to the RTX 5080.
Finally, reminiscence bandwidth alone isn’t sufficient to find out total gaming efficiency. Too little and you may be assured a graphics card will underperform, however the total efficiency of the RTX 5080 can be an interaction of the variety of processing cores within the GPU, the pace of the GPU and the pace of the reminiscence.
You’ll be able to study extra about all the pieces we all know up to now to do with the RTX 5080 in our Nvidia GeForce RTX 5080 information, however in the event you’re on the lookout for a cut price proper now, you may try our Amazon Prime Day offers web page for some graphics card reductions.
