Really, he claims to have overclocked the cardboard even additional than that. A cryptic tweet immediately says “RTX 4090 1.2v 800 3.5g🤔”. That may be 1.2 volts core, 800 watts energy draw, and three.5 GHz. The emoji might point out that he is solely considering such a factor, however the energy draw appears off to us given his already-achieved outcomes.
These outcomes come within the type of GPU-Z screenshots displaying the cardboard in varied states. The primary shot, partially reproduced above, exhibits the cardboard working 2730 MHz below a 97% load and drawing 446.9 watts whereas doing so. That is inventory efficiency, and the GPU stays cool at a most temperature of 73.4°C regardless of the low 1652 RPM fan pace, which is 40% of the utmost. The subsequent shot is the extra attention-grabbing one.
This screenshot shows the RTX 4090 idling after a benchmark or stress take a look at—observe the tiny inexperienced textual content indicating that sure settings are exhibiting minimal or most values. The GPU clock throughout the take a look at apparently hit 3,135 MHz, and the minimal temperature exhibits that this was accomplished with out utilizing LN2 cooling. Moreover, the board energy draw (seen within the full picture) peaked at 492.8 watts—an additional fifty watts for an additional 400 MHz of GPU clock over the inventory pace.
Whereas that sounds unhealthy while you put it that manner, that is solely about 10% extra energy for 15% extra clock pace, which suggests it is in all probability an effectivity acquire—a minimum of, if these clock and energy numbers maintain up below a heavy load. There isn’t any assure of that, although; conduct in benchmarks not often carries over to real-world workloads.
Early this morning, wxnod tweeted once more, with a brand new screenshot, reproduced above. That 3.24 GHz GPU clock is spectacular, however the extra attention-grabbing a part of this screenshot is the reminiscence overclock. 1562.7 MHz interprets to a GPU reminiscence information price of 25 Gbps for GDDR6X.
That is a 4-Gbps acquire over the inventory 21 Gbps reminiscence pace, and quicker even than the rumored 24 Gbps information price. That may give the cardboard some 1.2 TB/s—sure, that is terabytes-per-second—of reminiscence bandwidth. That is increased reminiscence bandwidth than you may discover on most GPUs geared up with HBM.
The overclocker did not go away this efficiency rotting on the vine. Testing in PUBG, he posted up the above screenshot exhibiting the cardboard hitting some 330 FPS common in PlayerUnknown’s BattleGrounds. That does not sound spectacular till you understand that the cardboard is doing it in native 4K decision, with out upscaling or body technology.
Pay no thoughts to the “RTX 3090TI SPUER PRO MAX PLUS” label; there is no manner something however a 4090 is hitting 3.1 GHz at “simply” 555 watts. The world document for an RTX 3090 Ti is round 3 GHz, and that required LN2 cooling. It isn’t like wxnod is aiming on the sky to supply an unrealistic framerate, both; the proven 1% low framerate is 243 FPS and you may clearly see a distant hilltop in his scope even within the cropped screenshot.
These sorts of overclocking outcomes lend some credence to rumors that the cardboard might scale upward for tons of of watts. Certainly, leather-based jacket aficionado (and NVIDIA CEO) Jensen Huang stated throughout the reveal of the playing cards that the corporate had overclocked Ada fairly excessive in its labs. Hopefully the vast majority of the playing cards clock in addition to wxnod’s pattern.
