NVIDIA GeForce RTX 3080 / RTX 3080 Ti 20 GB Graphics Card Alleged Specifications & Benchmarks Leak Out, On Par With An RTX 3090

Submit

The first performance numbers of NVIDIA's GeForce RTX 3080 20 GB or GeForce RTX 3080 Ti graphics card have allegedly leaked out. The numbers show that the upcoming graphics card features a performance on par with the existing flagship, the GeForce RTX 3090, & should also come with a lower price point.

NVIDIA GeForce RTX 3080 20 GB / GeForce RTX 3080 Ti Alleged Specs & Performance Benchmarks Leak Out

Posted over at Bilibili, the card is allegedly being referred to as the GeForce RTX 3080 20 GB but it also comes with an updated core configuration over the 10 GB model. As such, we could either see this card being labeled simply as the GeForce RTX 3080 20 GB or the GeForce RTX 3080 Ti with the latter making more sense based on previous rumors.

NVIDIA GeForce RTX 3080 Ti / RTX 3080 20 GB 'Rumored' Graphics Card Benchmarks

NVIDIA's GeForce RTX 3080 Ti / RTX 3080 20 GB FE (Founders Edition) graphics card is expected to feature the PG133-SKU15 PCB design and the GA102-250-KD-A1 graphics core. The GA102-250 GPU has also changed since the last time we saw them and is now exactly the same as the GeForce RTX 3090 at 10496 FP32 CUDA cores. The GPU will also feature the same 112/328 ROP & TMUs count as the RTX 3090. The clock speeds are set at 1395 MHz base and 1695 MHz boost.

As for memory, the card will feature 20 GB of GDDR6X memory. Unlike the 19.5 Gbps speeds of the RTX 3090, the GeForce RTX 3080 Ti is said to retain the same memory speeds as the RTX 3080 at 19 Gbps. Since we are getting a 20 GB bus interface, NVIDIA will be using a 320-bit bus interface which equals a total bandwidth of 760 GB/s. TGP for the card is set to be the same as the RTX 3080 at 320 Watts. That's definitely needed to feed the extra cores so NVIDIA might have to optimize the clocks a bit here.

NVIDIA GeForce RTX 3080 Ti / RTX 3080 20 GB 'Alleged' Graphics Card Benchmarks

Custom GALAX & Gainward GeForce RTX 3060 Cards With NVIDIA Ampere GA104 GPUs Listed

Two performance metrics were shown which include 3DMark Time Spy, Firestrike, Port Royal. In all tests, the GPU performed almost on par (5% average difference) with the GeForce RTX 3090 which was pretty much as expected. The benchmarks can be seen below:

Our Twitter buddy, Harukaze5719, has prepared a detailed chart based on all of the above-stated performance numbers which you could see below:

NVIDIA GeForce RTX 3080 Ti / RTX 3080 20 GB 'Alleged' Mining Performance

The leaker also posted some mining numbers for the said graphics card. The presumed GeForce RTX 3080 Ti / RTX 3080 20 GB graphics card was able to deliver an Ethereum mining rate of 125.3 MH/s while consuming 267 Watts of power and with temperatures hovering at around 48C.

The NVIDIA GeForce RTX 3080 Ti or the GeForce RTX 3080 20 GB (whichever name NVIDIA wishes to use for this card), will be a direct competitor to AMD's Radeon RX 6900 XT which retails at $999 US. Considering the availability of high-end graphics cards these days, both cards will be very hard to find in the retail segment.
