As we move through the Summer period, the end of the year looms closer and closer. To a lot of (crazy) people that means already making plans for Christmas, but there’s another end-of-year event to look forward to: the next generation of graphics cards from Nvidia and AMD (and now Intel! Hopefully)...
As such, rumors are coming in fast from loads of leakers online, including the latest exciting news from Kopite7kimi, who has regularly leaked accurate information in the past. Their new information says that the upcoming RTX 4090 could reach clock speeds close to 3GHz out of the box, and that’s without any third-party cooling solutions or overclocking.
RTX 40 series rumored specs
| GPU | CUDA Cores | Base Clock (MHz) | Boost Clock (MHz) | Memory (GB) | Memory Type | Bus Width | Memory Speed | TDP |
| RTX 4090 | 16384 | 2235 | 2520 | 24GB | GDDR6X | 384-bit | 21Gbps | 450W |
| RTX 4080 | 10240 | - | - | 16GB | 256-bit | 420W | ||
| RTX 4070 | 7168 | - | - | 10GB | GDDR6 | 160-bit | 18Gbps | 300W |
According to the report, the RTX 4090 will have a base clock speed of 2235MHz, and a boost clock speed of 2520MHz. That’s already pretty impressive considering the RTX 3090 hits speeds of 1670MHz for the base clock and 1860MHz for the boost clock already. However, considering many RTX 30 series GPUs will actually exceed the boost clocks, the RTX 4090 will supposedly reach over 2750MHz for its “actual max”.
Coupled with 16384 CUDA Cores, and a reported TDP of 450W, the RTX 4090 really does sound like quite the performance beast. We’ve heard previous rumors of massive performance leaps over the RTX 30 series, and with this new info it certainly seems likely.
And that’s all without even considering that an RTX 4090 Ti will also be likely in the future, with more CUDA cores, higher clock speeds, and of course a higher power draw. Which in all likelihood is the reason we’ve heard some crazy numbers like 600W-800W TDP. But Nvidia will unlikely release it before the RTX 4090, RTX 4080, and RTX 4070.
Speaking of those last two cards more details have come out regarding their specs, stating that the RTX 4080 will include 16GB of GDDR6X memory across a 256-bit interface (down from 320-bit bus width on the RTX 3080). Similarly, the RTX 4070 has also been downgraded to a 160-bit bus width, compared to 256-bit on the RTX 3070. Though memory speeds are up, with 21Gbps and 18Gbps on the RTX 4080 and RTX 4070 respectively.
What do you think? Are you excited for the RTX 40 series? How do you feel about the rumored specs above? Do you think they will make for a meaningful upgrade? And how do you feel about the downgraded bus size on the RTX 4080 and RTX 4070? Let us know!

If the price rumors are correct and they'll wants over 2K for those cards - screw 'em... I ain't paying that.

If I had to guess, I would say it probably won't be above 50% faster, I could see it going for 30-40% but we will see. Since it is new architecture and you can't exactly take clock count and core count and calculate it out fully, since there still are architectural improvements, be it IPC or otherwise. As for what is more important, I always was more of a practical man, I care about performance level, combined with power and especially cost. Whether they achieve performance with cores, clock, IPC, smaller node, memory or memory bandwidth, I really don't care.. Since in the end, everything can effect performance in this or that way.
Also I am not really top end buyer anyway, so huge power requirements there won't really effect me as much. Since at best, if 4070 is 500USD, I might be interested, but I am not really interested in top end. Plus I am looking forward to see what AMD is cooking too. RDNA could be quite a contrast in terms of power requirements.

So we should get rdy to put pcs into mini freezers

And DIY VRAMs yourself to make that 4070 a 12GB version
