In response to a publish within the Chiphell boards, considered one of its customers managed to benchmark Nvidia’s now-cancelled RTX 4080 12GB graphics playing cards. Sadly, efficiency was very poor for an RTX 4080-class GPU, with 3DMak Fireplace Strike and TimeSpy scores that solely matched Nvidia’s Ampere-based RTX 3080 12GB. That efficiency is disappointing, contemplating that the RTX 4080 12GB was technically supposed to exchange the RTX 3080 12GB.
The unique supply by no means disclosed the precise RTX 4080 12GB mannequin that was examined. Nonetheless, the poster nonetheless confirmed us the entire GPU monitoring information, together with core clocks, thermals and energy, so we have now a good suggestion of how these playing cards behave.
To refresh your reminiscence, the RTX 4080 12GB was Nvidia’s lowest-end Ada Lovelace GPU initially introduced throughout GTC, alongside the 4080 16B and 4090. The 4080 12GB was armed with an AD103 die, operating on 9728 CUDA cores, a 256-bit large bus and 22.6Gbps of GDDR6X reminiscence, for a complete of 717GB/s of bandwidth.
However after extreme criticism by the group, Nvidia canceled the RTX 4080 12GB mannequin as a result of its very complicated title in comparison with the RTX 4080 16GB. The 4080 12GB options considerably altered core specs in comparison with the 16GB model regardless of the names solely suggesting there can be a capability distinction between the playing cards.
Nonetheless, Nvidia’s “unlaunch” got here after RTX 4080 12GB playing cards began rolling off manufacturing strains; that is how the Chiphell consumer managed to snag a card.
In response to the GPU-Z picture from the Chiphell discussion board publish, this unnamed RTX 4080 12GB mannequin was working at a most real-world enhance clock of two,820 MHz, and a 1,313 MHz reminiscence clock. Thermals have been within the 72.3C vary at their max, with sizzling spot temps hitting 91.2C. Fan speeds at their max have been at 43%, however the RPM is unknown. Energy consumption might be seen hitting 261W at its peak.
This monitoring information proves to us that the RTX 4080 12GB was severely lower down in comparison with the RTX 4080 16GB and RTX 4090. The clocks stay much like the 4090, however energy consumption is considerably lowered to only 262W. The cardboard was not energy throttling as a result of an influence restrict, as demonstrated by GPU-Z’s peak TDP of simply 91.8% of the full energy goal.
However the 4080 12GB’s efficiency in 3DMark says all of it. In response to the Chiphell publish, the RTX 4080 12GB examined managed a GPU rating of simply 13,472 factors in 3DMark Fireplace Strike Extremely and 10,794 factors in TimeSpy Excessive.
For comparability, these numbers translate into equal to barely higher efficiency than an RTX 3080 12GB in the very same benchmarks, based on 3DMark’s benchmark browser. It is price noting that the 30 collection GPUs within the browser’s outcomes have been manually overclocked, however nonetheless, meaning the RTX 4080 12GB sits proper in between a inventory RTX 3080 12GB and RTX 3080 Ti.
It is simple to see why Nvidia cancelled the RTX 4080 12GB when it did, the RTX 4080 12GB initially had an MSRP of $900 when introduced. However with the efficiency numbers we see right here, the GPU would not even be an enchancment over Nvidia’s older RTX 3080 12GB or RTX 3080 TI which might be discovered for effectively beneath $900 proper now.
