NVIDIA RTX3080 feature

Here are some alleged specs and benchmarks of Nvidia’s rumored RTX 3080/Ti 20GB “Ampere” GPU

It appears that some gaming performance benchmark numbers and alleged specs of NVIDIA’s GeForce RTX 3080/RTX 3080 Ti 20 GB graphics card have leaked out. One Chinese content creator “Big hardware player” got access to an engineering sample of the GeForce RTX 3080 20GB GPU, and has posted his findings over at Bilibili, coming via @9550pro.

But before continuing, please bear in mind that this leak might seem a bit fishy, since we can’t verify whether the leaker indeed has this GPU with him, and more importantly, the GPU-Z software database has not been updated for this GPU yet by TechPowerUp. So exercise some caution here. Still, there’s a huge chance none of this is legitimate.

With that being said, we are looking at Nvidia’s unreleased GPU which happens to be either the RTX 3080 20 GB or the RTX 3080 Ti/SUPER 20GB SKU (assuming Nvidia chooses this Ti nomenclature instead). In either case, this GPU sports 20GB of GDDR6X VRAM and has beefier specs than the already released RTX 3080 10GB SKU.

The manufacturer of this card happens to be the COLORFUL brand as evident from the GPU-Z “subvendor” and device entry/ID. Coming to the specs, RTX 3080 Ti/RTX 3080 20GB GPU is expected to feature the PG133-SKU15 PCB, and the GA102-250-KD-A1 graphics core. For comparison, the GeForce RTX 3090 rocks the GA102-300 GPU.


We expect this 20GB GDDR6X memory SKU to feature similar specs as the RTX 3090 GPU, sporting 10496 FP32 CUDA cores, and 112/328 ROP & TMU counts, respectively. The clock speeds should be 1395 MHz for the base and 1695 MHz for the boost.

But unlike the RTX 3090, the 20GB GeForce RTX 3080/3080 Ti retains the same memory speeds as the RTX 3080 at 19 Gbps. The RTX 3090 GPU on the other hand has 19.5 Gbps as the memory speed. Moreover, the card will have the same 320-bit bus interface which provides a total bandwidth of 760 GB/s.

TDP for the card is also set to be the same as the RTX 3080 at 320 Watts, though the leaker claims the TDP can be increased to 350 Watts as well, which is the same as the RTX 3090 GPU to feed the extra GPU cores.

For the testing the user also appears to have used an engineering driver for this GPU variant, which might seem a bit unusual. Here are some of the red flags in this leak, which makes these benchmarks even more suspicious.

First off, the GPU-Z registers the card as a vanilla RTX 3080; however the specs seem to match with the RTX 3090. But there were rumors before that this 20GB SKU will sport similar specs as the current flagship RTX 3090 GPU. Maybe NVIDIA will drop the Ti nomenclature?

Next, the GPU driver version is blurred out in the GPU-Z screenshot of the RTX 3080 20GB SKU. Moreover, the leaker has used driver version 456.16 on the 3080 10GB, and version 456.71 on the 3090 GPU. Why use different GPU driver versions in the same test? Why blur out the entry?

Apart from that, the GPU-Z “subvendor’ entry/ID is also blurred out, which actually reveals the manufacturer, but the leaker claims the card is from Colorful brand.

Also, note the WHQL drivers from December 3 being used on the 3080 Ti GPU. All three GPUs have a different driver version date, which seems a bit odd! Moreover, GPU-Z version 2.35.0 was used on the 3080 Ti, while version 2.36.0 was used on the RTX 3090 and version 2.34.0 was used for the RTX 3080 10GB variant. Again, three different versions used for the same test ?

Nonetheless, here are some gaming benchmark screenshots, along with some synthetic benchmark scores as well. In most of the tests, the GPU performed almost on par (3-5% average difference) with the GeForce RTX 3090 GPU. The GPU was paired with an AMD Ryzen 9 5950X CPU, running on Windows 10 pro OS, version 1909.

So basically the NVIDIA GeForce RTX 3080 Ti or the GeForce RTX 3080 20 GB will be a direct competitor to AMD’s Radeon RX 6900 XT flagship GPU which currently retails for $999 USD. The RTX 3090’s MSRP is set at $1499, so we expect this RTX 3080 20GB SKU to have a price tag of approx max $999 USD.

But the availability is going to be a huge issue, given the recent demand and supply market trend.

So don’t expect this card to be easily sold in retail shelves at least at the MSRP value set by Nvidia. AIBs on the other hand are obviously going to charge a premium for their custom models.

The performance of this SKU seems to be on par with the current flagship RTX 3090 GPU, but it remains to be seen where this GPU will fit in the performance hierarchy, given its price tag.

Hello, my name is NICK Richardson. I'm an avid PC and tech fan since the good old days of RIVA TNT2, and 3DFX interactive "Voodoo" gaming cards. I love playing mostly First-person shooters, and I'm a die-hard fan of this FPS genre, since the good 'old Doom and Wolfenstein days. MUSIC has always been my passion/roots, but I started gaming "casually" when I was young on Nvidia's GeForce3 series of cards. I'm by no means an avid or a hardcore gamer though, but I just love stuff related to the PC, Games, and technology in general. I've been involved with many indie Metal bands worldwide, and have helped them promote their albums in record labels. I'm a very broad-minded down to earth guy.
