The latest specifications of NVIDIA's GeForce RTX 3080 Ti graphics card have leaked out by our pals at Videocardz. The graphics card's Ampere GA102-225 pictures have leaked out though there is still some confusion as to whether this chip will be the final variant for the card itself or there's a newer version of the GPU SKU.
The Ampere GA102-225 GPU Which Powers The NVIDIA GeForce RTX 3080 Ti Graphics Card Has Been Pictured
In addition to the newly leaked GPU pictures and specifications, Videocardz also got hold of the initial mining performance numbers of the card. Now we are aware that NVIDIA is using a more strict BIOS Firmware lock to enforce hash rate limit on the GeForce RTX 3080 Ti graphics card & revised Ampere cards but it is possible that this particular sample that was tested is an early chip that could be one of the qualification samples that didn't implement the new hardware locks to prevent it from use in mining operations.
As such, the NVIDIA GeForce RTX 3080 Ti sample tested in the leak delivers a mining hash rate of around 119 MH/s (after optimizations) in Ethereum. The card has been tweaked as you can see by its TDP of 278W which is nowhere close to what this GPU would deliver at stock. The memory has also been tweaked to operate at 21.4 Gbps instead of its standard 19 Gbps out-of-the-box speeds.
NVIDIA GeForce RTX 3080 Ti 12 GB 'Rumored' Graphics Card Specifications
NVIDIA's GeForce RTX 3080 Ti 12 GB FE (Founders Edition) graphics card is expected to feature the PG132-SKU18 PCB design and the GA102-225-KD-A1 graphics core. The GA102-225 GPU has also changed since the last time we saw them and will now feature 10240 CUDA cores within a total of 80 SM units. The GPU features a clock speed of 1365 MHz base and 1665 MHz boost, both of which are slower than the existing GA102 GeForce RTX GPUs.
ITHome has reported that the final NVIDIA GeForce RTX 3080 Ti graphics card is expected to ship with the new GA102-202 or GA102-302 GPU core features the same specifications as the QS but is locked for mining.
As for memory, the card will feature 12 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 12 GB memory, the NVIDIA GeForce RTX 3080 Ti will be using a 384-bit bus interface which equals a total bandwidth of 912 GB/s. So while we see an 8 GB VRAM reduction over the previous spec, the larger bus interface should drive higher memory bandwidth.
The 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. The NVIDIA GeForce RTX 3080 Ti is expected to feature an MSRP of around $999 US while ITHome has reported that a price of 7999 Chinese Yuan which is equal to around $1200 US is expected in the APAC retail market. The card is rumored to launch in May.
