How GDDR7 reminiscence would possibly repair PC gaming VRAM points

Micron simply introduced that a number of the finest graphics playing cards may get a significant increase quickly, and this announcement could not have come at a greater time.

In keeping with Micron, the next-generation GDDR7 reminiscence customary is anticipated to launch within the first half of 2024. Will this deal with rising issues about VRAM limits, or will it merely contribute to the continued rise in GPU costs?


Whereas GDDR6/GDDR6X are the present video reminiscence requirements in graphics playing cards, it is time to transfer on – the know-how has been round since 2018, which is a very long time within the pc {hardware} world. Micron has an answer within the type of GDDR7 and spoke about its plans throughout its current earnings name. To date, it seems like the whole lot is on observe and GDDR7 reminiscence will hit the market in lower than a 12 months, however that does not imply we’ll see it in GPUs straight away.

As soon as GDDR7 is right here, it’s going to definitely supply an enormous bandwidth increase, and that might be a lifesaver for playing cards with a small reminiscence bus, just like the RTX 4060 Ti or RX 7600. high-end will certainly profit.

Wccftech reviews that Micron is aiming for 36Gbps of bandwidth per pin, whereas the present most is round 22Gbps in Nvidia’s GDDR6X options and 20Gbps for AMD’s GDDR6 choices. The per-pin bandwidth improve will dramatically enhance the reminiscence bandwidth for any GDDR7 geared up GPU. For instance, a finances card with a 128-bit bus will now supply 576Gbps of bandwidth, which is a large step ahead. Larger-end fashions, just like the RTX 4090, will be capable to hit a whopping 1.7TB/s of reminiscence bandwidth up from the present most of 1TB/s.

This increase will come courtesy of Micron’s newest 1ß (1-beta) node, which makes use of deep ultraviolet (DUV) lithography. The subsequent node, referred to as 1y, will change to excessive ultraviolet (EUV) lithography.

Micron’s announcement is, in actual fact, completely timed. There was lots of speak concerning the points that restricted VRAM and reminiscence bandwidth could cause in gaming situations. Nvidia has acquired fairly a little bit of backlash for its $400 RTX 4060 Ti, which sports activities simply 8GB of VRAM on a 128-bit bus. Think about how a lot better that card would have fared if it already had the GDDR7 RAM to offer it that essential bandwidth increase.

Micron’s launch timing can be fairly nice. Nvidia does not plan to launch a sequel to its RTX 40-series graphics playing cards till 2025, so that offers it sufficient time emigrate to GDDR7. AMD is prone to observe swimsuit, though they nonetheless have a somewhat small lineup of RDNA 3 playing cards that should be compiled earlier than shifting as much as the following technology.

Nevertheless, there’s a draw back to GDDR7, which is that it’s going to possible trigger GPU costs to rise. On condition that a number of the newest technology playing cards are already extraordinarily costly, this doesn’t bode effectively for our wallets.

It additionally signifies that the GPUs that want this improve essentially the most — mid-range and entry-level playing cards with a slim reminiscence bus — in all probability will not get it for a while. We may even see an RTX 5090 with GDDR7X VRAM, however the RTX 5060 might not be as fortunate. In fact, nothing is definite proper now, so we’ll simply have to attend and see.
