The GALAX HOF OC Lab edition for the Chinese-RTX 5090 D V2 variant has a very similar design to the RTX 5090 D HOF OC Lab Plus-X, but has lower VRAM and boost clock.
GALAX RTX 5090 D V2 HOF OC Lab Plus-X Tested Against RTX 5090 D; Similar Performance but Manages to Outperform Latter With Overclocking
GALAX recently released the HOF OC Lab Plus-X edition for the new Chinese RTX 5090 variant called RTX 5090 D V2. The company already had a couple of HOF OC Lab editions for the GeForce RTX 5090 D, which was the first RTX 5090 variant for the Chinese market, banned in the mainland due to US export policies. GALAX RTX 5090 D V2 HOF OC Lab Plus-X is now the flagship RTX 5090 D V2 GPU to buy and has very similar PCB layout to the RTX 5090 D edition.
A reviewer on Bilibili showcased the GPU, revealing that the RTX 5090 D V2 HOF OC Lab Plus-X has the traces for two 16-pin power connectors but only ships with one. This PCB has been used across all the RTX 5090 D HOF editions, since it was originally designed for the RTX 5090 D HOF OC Lab XOC, which shipped with two 16-power connectors. The GPU was, unfortunately, banned by the US government soon after release. However, GALAX just came up with the HOF edition for the RTX 5090 D V2, which is now in the hands of some reviewers and enthusiasts.
The PCB reveals identical VRM design, featuring 36 power phases. The only two differences are the absence of a few VRAM chips, and a single 16-pin power connector, since it's a downgraded RTX 5090 GPU, which has to meet US export policies. The TDP has also been reduced from 600W to 575W, and therefore, dual 16-pin power connectors are no longer needed.
In gaming and synthetic workloads, the GPU is on par with the RTX 5090 D, which is obvious since there isn't any noticeable difference between the two except for lower VRAM on the RTX 5090 D V2. Since 24 GB VRAM capacity is more than enough, there is no performance regression seen on the newer card. The V2 ships with the same 21,760 CUDA cores, but a 384-bit memory bus compared to 512-bit. Nonetheless, with some overclocking, the RTX 5090 D V2 HOF OC Lab Plus-X was able to beat the RTX 5090 D with a small margin.
The reviewer bumped up the memory clock by 1600 MHz and the core clock by 310 MHz (table showed 2610 MHz as the default boost clock, so around 2920 MHz with overclocking), which the card was able to handle without breaking a sweat. This is exactly what the HOF cards excel at, and it's possible to easily go past the 3.0 GHz on the RTX 5090 D V2 as well. But even with minimal efforts, the RTX 5090 D V2 is able to deliver slightly better gaming performance. We didn't get to see the AI performance comparison, but previously, we did see RTX 5090 D V2 getting beaten convincingly in such workloads.
