News Micron says GDDR7 will provide a 30% improvement in gaming — both ray tracing and rasterization

[Admin]

In a press release, Micron revealed that its GDDR7 will provide 30% greater frame rates than its older GDDR6 memory in ray tracing and rasterized video games.

According to rumors and leaks, Nvidia will be the first to produce graphics cards with GDDR7 modules.

And even then so, only the flagship RTX 5090/5080 cards might sport these modules, that too utilizing 28Gb/s speed as the minimum, let alone using 32Gb/s and higher spec'd variants.

BTW, speaking of GDDR7 memory and Nvidia's Blackwell GPU lineup.

There was an update that the next-gen RTX 5090 GPU will reportedly sport 28GB GDDR7, on a 448-bit bus !

So it will not use all the available 512-bit memory bus of the GB202 die, and only 14 memory modules would be used out of 16 (see below). So that should give 28GB VRAM, out of 32GB total. More than enough for any gaming GPU.

They could reserve the remaining VRAM for later Ti variants, if need be, or use it on a "ProViz" RTX GPU.

Assuming Nvidia goes for 28 Gbps GDDR7 memory modules initially, then we could see a total bandwidth of up to 1568 GB/s on the RTX 5090, which is still 56% more bandwidth than the RTX 4090 (384-bit @ 21 Gbps).

Also, it is rumored that the RTX 5090 would feature a 3 PCB design, on the Founders Edition/FE model. There are also four memory modules on the top, five each on the sides, and two at the bottom.

So we get a total of 16 GDDR7 DRAM modules featured on the RTX 5090 PCB. But not clear as to whether that refers to three individual PCBs within a single card, or three unique designs of which only one should be finalized.

The memory layout is very dense.

FE uses three PCBs to leave space for double-sided blowing. The 30 and 40 dovetails are single-sided blowing, you know what I mean.
Because the bit width is increased, the PCB cannot hold the memory lying down, and the staggered layout like PG651 is not used, so the full blowing method of PG137 is not inherited.

The thing I'm most curious about is latency as the implication is that they've improved the latency which means to me mostly that they didn't have to blow it up to get the extra bandwidth. It's nice to see the signaling shift so we don't end up with Micron going it alone with GDDR7X with PAM4 for high bandwidth.

30% on a 4060ti puts it on pair with a 4070 super...

Another bull.hit claims


They need tell on the fatest avaliable graphics card with gddr7 can have a uplift of 30%.

If your cpu can do it... right now? No one can do it

Nvidia: yes, but just means we have to gimp the bus to reduce performance by 30% to compensate on the xx60 gpu's in future!

Meanwhile, see this MOD in action till we dream of getting GPUs sporting some of the highest rated memory speeds. Enter RTX 4090 SUPER ! 🤠

Don't fall for this though, 'cause such gains can only be observed under specific circumstances and test environment, and the app/software in question should be extremely bandwidth-starved/hungry as well.
