News World's first 'RTX 4090 Super' scores up to 16% higher than standard 4090 — Custom liquid cooled GPU has 3090 Ti PCB and faster GDDR6X

I'm confused. They got the PCB from a 3090ti and the VRAM was 25.8Gbs? The 3090ti came out with 21Gbs, the same as the 4090

No, they used the Galax HOF RTX 3090Ti's PCB, but replaced the board's 21 Gbps GDDR6X memory modules with RTX 4080 SUPER's memory modules rated for 24Gbps, although this GPU only supported 23 Gbps out of the box.

Then, they overclocked it to 26 Gbps. 4080 Super's binned 24 Gbps GDDR6X (ZF) modules were used.

So in the end, the modded "RTX 4090 SUPER" graphics card featured the AD102-300-A1 "Ada" GPU die, and had its memory replaced with binned 24 Gbps GDDR6X (ZF) modules.

So they put a 4090 on a 3090Tis PCB. I didnt know the GPU pins were compatible across generations. Damn, whats intel even doing.

Yes, GA102 is pin-compatible with AD102.

In fact, the RTX 3090 Ti card was used as a "Test vehicle", and as a learning curve by NVIDIA and its AIB partners, before the RTX 40 series came out.

And since Ampere "GA102" and Ada Lovelace "AD102" GPUs were likely pin-compatible, they could be featured on similar PCB designs, or ones with very little modifications. So AIBs weren't forced to design completely brand new boards either.
