Rumor | More Nvidia Lovelace RTX 4090, RTX 4080, and RTX 4070 specs leak, RTX 4060 also rears its head but with 4 GB less VRAM than RTX 3060
We have been seeing the occasional leak or two pertaining to Nvidia's upcoming Lovelace AD102 GPU. Now, an unverified list of upcoming RTX 40 series has leaked on Chinese website Bilibili. This includes specifications of the RTX 4060, RTX 4070, RTX 4080, and the RTX 4090 such as CUDA core counts, memory specs, and TGPs compared to their RTX 30 series counterparts.
According to the leak, the configurations are as follows:
| Spec | RTX 4090 | RTX 4080 | RTX 4070 | RTX 4060 |
|---|---|---|---|---|
| GPU | AD102 | AD103 | AD104 | AD106 |
| Streaming Multiprocessors | 126 | 84 | 60 | 36 |
| CUDA Cores | 16,128 | 10,752 | 7,680 | 4,608 |
| Memory Configuration | 384-bit 24 GB GDDR6X | 256-bit 16 GB GDDR6X | 192-bit 12 GB GDDR6X | 192-bit 8 GB GDDR6X |
| TGP | 450 W | 350 W | 300 W | 200 W |
We've already seen some of this information in earlier leaks, so this info does seem to lend further credence to those leaks. This time, we might get to see Nvidia use different GPUs for each SKU instead of reusing binned dies. The flagship RTX 4090 "BFGPU" could top out at 16,128 CUDA cores as leaked before. The very first leaks hinted at the full AD102 die featuring 18,432 CUDA cores, so it is likely that Nvidia would save it for a "4090 Ti" refresh down the line.
The RTX 4090 potentially packs 53% more CUDA cores than the RTX 3090. Factor in things like IPC increase, better efficiency due to the TSMC 6 nm, and the works, and we are staring at potentially double the performance compared to an RTX 3090.
Similarly, the RTX 4080 offers 23%, the RTX 4070 offers 25%, and the RTX 4060 a 26% increase in CUDA core counts over their corresponding RTX 30 Ampere counterparts.
We have also seen hints about an AD103 RTX 4080 and an AD104 RTX 4070 before. Now, we are also getting to know the specifications of the RTX 4060 for the first time.
The RTX 4060 is rumored to be based on the AD106 GPU with 36 streaming multiprocessors (SMs) and 4,608 CUDA cores. The card is rated for a total graphics power (TGP) of 200 W, which is about 30 W higher than that of the RTX 3060.
That catch here, though, is the 192-bit 8 GB of GDDR6X VRAM. We are not quite sure as to why the RTX 4060 is rumored to offer 4 GB less VRAM than the RTX 3060, that too with a similar memory configuration.
While there's a high probability for this leak to be true, it still helps to take it with a pinch of the proverbial salt until official reveal.
