The AMD Radeon RX 7900 XTX graphics card has been examined with all of its energy limits eliminated and attracts as much as an insane 700W of energy.
Even A 700W AMD Radeon RX 7900 XTX Can not Beat A Inventory NVIDIA GeForce RTX 4090 GPU
Fanatic overclocker, Jedi95 from the AMD Subreddit, determined to place his {custom} AMD Radeon RX 7900 XTX graphics card to the take a look at utilizing the Elmor Labs EVC2SE and a few DIY mods on the PCB to unlock its energy limits. The graphics card used was an ASUS TUF variant which was outfitted with a EK Quantum Vector water block custom-loop cooling resolution that was connected to a water chiller with a coolant temp of 10C.
The modification allowed the fanatic to regulate each energy consumption and the present of the GPU and permit it to be configurable by way of software program. The AMD Radeon RX 7900 XTX was examined throughout numerous benchmarks and hit a mean GPU clock of three,333 MHz in 3DMark Time Spy & a peak GPU clock velocity of three,467 MHz in the identical benchmark.
When it comes to efficiency, the overclocked AMD Radeon RX 7900 XTX GPU scored 38,725 factors in 3DMark Time Spy, 19,137 factors in 3DMark Time Spy Excessive, 20,492 factors in 3DMark Port Royal, and seven,690 factors in 3DMark Speedway benchmarks. These are graphics factors which matter extra and based mostly on the numbers, the GPU did come very near the NVIDIA GeForce RTX 4090.
The extra essential factor right here is that the AMD Radeon RX 7900 XTX consumed as much as 700 Watts of energy (696W to be precise). That is virtually twice its rated TBP of 355W and whereas the benchmarks are an enormous improve over the inventory 7900 XTX, it nonetheless would not handle to outrightly beat the NVIDIA 4090. In actual fact, our barely overclocked GeForce RTX 4090 was on par within the Time Spy benchmarks and had an enormous lead within the Speedway and Port Royal benchmarks, all of that whereas operating near 400-500W energy.

Again in March, AMD mentioned that it was solely doable to develop an NVIDIA GeForce RTX 4090 rival based mostly on the RDNA Three GPU structure however they determined to not go there because of worth & GPU energy constraints. Now we all know why that was the case. If AMD needed to launch a card above the 7900 XTX or a variant of it that tackled the 4090, it might have been an influence hog which meant that AMD could be shedding out huge on effectivity and would even have required a lot beefier cooling. NVIDIA is utilizing a triple-slot behemoth for its 4090 and the identical would have been the case to chill over 500 Watts of energy coming from a GPU of this tier. In the long run, this can be a showcase of what might’ve been an AMD flagship providing.
It appears like we must watch for a technology or two earlier than AMD’s chiplet design matures sufficient for the corporate to launch an ultra-enthusiast providing that tackles NVIDIA’s high-end whereas being environment friendly.
