Just yesterday, we came to learn about a new spec of the NVIDIA GeForce RTX 4070 graphics card and it looks like Kopite7kimi has more information to share.
NVIDIA GeForce RTX 4070 Graphics Card "Rumored" Specs: 7680 Cores, 12 GB GDDR6X, 285W TGP & More TFLOPs Than An RTX 3090 Ti
As per the previous rumor, we came to know about a third spec change for the GeForce RTX 4070 graphics card which is expected to cost more or less the same as the RTX 3070. Previous rumors have positioned the card as a GeForce RTX 3090 Ti replacement at 1/4th the price ($2000 US MSRP). If that should be the case, then the GeForce RTX 4070 has the potential to become a very popular graphics card in the $500 US category.

NVIDIA GeForce RTX 4070 'Expected' Specifications
The NVIDIA GeForce RTX 4070 is expected to utilize the full-fat AD104 GPU core with 7680 cores or 60 SM units. From previous leaks, we also know that the AD104 GPU will come packed with 48 MB of L2 cache and up to 160 ROPs which is simply insane. That's a 25% increase in core count and a 12x increase in cache versus the GeForce RTX 3070 Ti which rocks the GA104 GPU core. The latest information reveals that the chip will have a base clock of 2310 MHz, a boost clock of 2610 MHz, & a maximum clock speed of up to 2800 MHz. That's over a 1.0 GHz clock difference between the RTX 4070 and RTX 3070 which is impressive but also expected considering NVIDIA is utilizing TSMC's 4N (optimized 5nm) process node for its Ada Lovelace GPUs.
At the maximum clock speed, the NVIDIA GeForce RTX 4070 should offer up to 43 TFLOPs of FP32 Compute horsepower which puts it ahead of NVIDIA's current fastest gaming GPU, the RTX 3090 Ti. The RTX 3090 Ti features a maximum FP32 compute of 40 TFLOPs while the RTX 3070 features a 20 TFLOPs compute horsepower. That's a 7.5% increase versus the RTX 3090 Ti and a 2x increase over the RTX 3070.
As for memory specs, the GeForce RTX 4070 is expected to rock 12 GB GDDR6X capacities that are said to be clocked at 21 Gbps speeds across a 192-bit bus interface for 504 GB/s bandwidth. As for power numbers, the RTX 4070 is now rated at 285W TGP which is 65W higher than the TGP of the RTX 3070. The graphics card is expected to be based on the PG141-SKU331 PCB design.

One thing should be pointed out that Kopite7kimi earlier stated that the 285W figure was TBP or total board power but has now suggested that it could be the TGP or Total Graphics Power.

The leaker also posted revealed the expected clock speeds of the RTX 4090 graphics card a while back which is expected to clock as high as 2.75 GHz with a TGP of 450W. The NVIDIA GeForce RTX 4080 and RTX 4070 graphics cards will be amongst the first graphics cards besides the RTX 4090 to launch to gamers however we can't tell whether the green team plans to launch them within this year soon after RTX 4090 or wait till early next year. The RTX 4090 is so far expected to launch around October 2022.
