NVIDIA GeForce RTX 4090 24 GB, RTX 4080 16 GB & RTX 4080 12 GB Specs Leak Out

Chinese GPU Supplier Rumored To Get First NVIDIA GeForce RTX 40 Graphics Cards In Less Than A Month

NVIDIA's GeForce RTX 4090 24 GB, RTX 4080 16 GB & RTX 4080 12 GB graphics cards specs have been leaked by Kopite7kimi.

NVIDIA GeForce RTX 40 Launch To Include 4090 24 GB, 4080 16 GB, 4080 12 GB As Per Latest Leak

A few days ago, we reported the alleged launch dates of the trio of GeForce RTX 40 graphics cards that NVIDIA is planning to launch in the coming months. Besides the launch dates, we also reported new specifications such as the TGP figures for the GeForce RTX 4080 16 GB & RTX 4080 12 GB cards which will feature very different specifications besides their names being the same.

So once again, It is reported that the RTX 4090 will indeed be showcased at GTC 2022 and that the card will be launching in October, which is something that we had stated back in June. Interestingly, the editor also states that the RTX 4080 is also going to launch a month after 4090 in November which is also something that we had said a few months ago in our exclusive.

  • NVIDIA GeForce RTX 4090 Graphics Card - October 2022 Launch
  • NVIDIA GeForce RTX 4080 Graphics Card - November 2022 Launch
  • NVIDIA GeForce RTX 4070 Graphics Card - December 2022 Launch
  • NVIDIA GeForce RTX 4060 Graphics Card - January CES 2023 Unveil

Besides the new information from Kopite7kimi, Videocardz has also shared new data which gives us an insight into the boost clocks of the three graphics cards and the maximum TGP that can be configured through the BIOS (not to be mistaken with actual TGP).

NVIDIA GeForce RTX 4090 24 GB 'Expected' Specifications

The NVIDIA GeForce RTX 4090 will use 128 SMs of the 144 SMs for a total of 16,384 CUDA cores. The GPU will come packed with 96 MB of L2 cache and a total of 384 ROPs which is simply insane but considering that the RTX 4090 is a cut-down design, it may feature slightly lower L2 and ROP counts. The clock speeds are not confirmed yet but considering that the TSMC 4N process is being used, we are expecting clocks at 2520 MHz. The GPU itself will be a 75 Billion transistor behemoth which will have a die size of around 600mm2.

As for memory specs, the GeForce RTX 4090 is expected to rock 24 GB GDDR6X capacities that will be clocked at 21 Gbps speeds across a 384-bit bus interface. This will provide up to 1 TB/s of bandwidth. This is the same bandwidth as the existing RTX 3090 Ti graphics card and as far as the power consumption is concerned, the TBP is said to be rated at 450W which means that TGP may end up lower than that. The card will be powered by a single 16-pin connector which delivers up to 600W of power. It is likely that we may get 500W+ custom designs as we saw with the RTX 3090 Ti.

  • NVIDIA GeForce RTX 4090 "Expected" TBP - 450W
  • NVIDIA GeForce RTX 3090 "Official" TBP - 350W

NVIDIA GeForce RTX 4080 16 GB 'Expected' Specifications

The NVIDIA GeForce RTX 4080 16 GB graphics card is expected to utilize a cut-down AD103-300 GPU configuration with 9,728 cores or 76 SMs enabled of the total 84 units whereas the previous configuration offered 80 SMs or 10,240 cores. While the full GPU comes packed with 64 MB of L2 cache and up to 224 ROPs, the RTX 4080 might end up with 48 MB of L2 cache and lower ROPs too due to its cut-down design. The card is expected to be based on the PG136/139-SKU360 PCB. The graphics card is said to offer a peak clock rate of 2505 MHz.

As for memory specs, the GeForce RTX 4080 is expected to rock 16 GB GDDR6X capacities that are said to be adjusted at 23 Gbps speeds across a 256-bit bus interface. This will provide up to 736 GB/s of bandwidth. This is still a tad bit slower than the 760 GB/s bandwidth offered by the RTX 3080 since it comes with a 320-bit interface but a lowly 10 GB capacity. To compensate for the lower bandwidth, NVIDIA could be integrating a next-gen memory compression suite to make up for the 256-bit interface.

  • NVIDIA GeForce RTX 4080 16 GB "Expected" TBP - 340W
  • NVIDIA GeForce RTX 3080 12 GB "Official" TBP - 350W

For power, the TBP is now set to be rated at 340W, a 20W increase from the previous 320W spec that we got. This brings the TBP to the same ballpark as the existing RTX 3080 graphics card (up to 350W). The maximum BIOS TGP is said to be rated at 516W. Now it is not known whether the other RTX 40 series graphics cards will also be getting the faster GDDR6X memory treatment but we know that Micron has commenced full mass production of up to 24 Gbps GDDR6X memory modules so they have to go somewhere.

NVIDIA GeForce RTX 4080 12 GB 'Expected' Specifications

The NVIDIA GeForce RTX 4080 will also feature a 12 GB variant that is expected to utilize the AD104-400 GPU configuration with 7,680 cores or 60  SMs enabled which is the full-fat SKU. The GPU will be packing 48 MB of L2 cache and features a 192-bit bus interface so that's why we are getting up to 12 GB of GDDR6X capacities. The memory is said to be running at 21 Gbps speeds for a memory bandwidth of 504 GB/s. The card is said to be clocked at a 2610 MHz boost clock however the peak frequency will be higher.

  • NVIDIA GeForce RTX 4080 12 GB "Expected" TBP - 285W
  • NVIDIA GeForce RTX 3080 10 GB "Official" TBP - 320W

For power, the TBP is now set to be rated at 285W which is a 35W decrease versus the RTX 3080 10 GB model. The card is expected to offer better performance than the RTX 3080 but given the specs cut over the 4080 16 GB, there will be a big gap between both models. The maximum BIOS TGP is said to be rated at 366W.
