No. Some 4090s had issues with power connectors. The 4090 does not support NVLink (though there is evidence that they were designed with the capability).

- marcyb5st 4y agoProbably they are using the same PCBs as their Datacenter counterparts and there NVLink is extremely important to minimize overhead.
- verall 4y agoThey're not using the same PCBs because 4090 has the blow-through cooler and so a downsized pcb but the DC cards have big fanless heatsinks for cooling by chassis fans. 3090 had nvlink so it was probably considered for 4090 but eventually cut for some reason
- gambiting 4y agoI imagine the reason was that hardly anyone used it, and those that did use it were the same group of clients who would traditionally buy Quadro cards.
- spookie 4y agoOh yeah, the artificial market segmentation.
- ChuckNorris89 4y agoIs there natural market segmentation as well?
- my123 4y agoThe AD102 die this gen doesn’t have NVLink on silicon. RTX 6000 Ada Generation doesn’t have NVLink, and neither does the L40.
- touisteur 4y agoIs the white paper out and precise specs available for L40? Last time I looked nvlink was still with a question mark on L40? Doesn't make sense to remove the nvlink feature from the A40 line that had some nvlink, that would piss off a bunch of users hoping to upgrade to not-H100...
- buildbot 4y agoEntertainingly, they do use molex micro fit connectors on SXM boards - the same ones as the 4090.
