Kopite7kimi, a well-known leaker on Twitter, has published what may be the first specifications of Nvidia's upcoming GeForce RTX 40-series graphics cards family. Since we are several months away from Nvidia's launch of its codenamed Ada Lovelace architecture, it's possible there will be changes, but given the leaker's track record, the specs are at least worth considering.
Nvidia's initial GeForce RTX 40-series family will consist of three graphics cards: the GeForce RTX 4090, based on the AD102-300 graphics processor paired with 24GB of GDDR6X memory; the GeForce RTX 4080, powered by the AD103-300 GPU mated with 16GB of GDDR6/GDDR6X memory; and the GeForce RTX 4070 featuring the AD104-275 chip equipped with 10GB of GDDR6.
The number of CUDA cores featured by Nvidia's Ada Lovelace GPUs show that the new graphics boards will likely have a considerable performance increase when compared to Nvidia's existing GeForce RTX 30-series, which are among best graphics cards around.
Rumored Nvidia GeForce RTX 40-Series Specifications
|Row 0 - Cell 0||GPU||FP32 CUDA Cores||Memory Configuration||TBP|
|GeForce RTX 4090||AD102-300||16384||24GB 384-bit 21GT/s GDDR6X||450W|
|GeForce RTX 4080||AD103-300||10240||16GB 256-bit 18GT/s GDDR6?||420W|
|GeForce RTX 4070||AD104-275||7168||10GB 160-bit 18GT/s GDDR5||300W|
All these initial GeForce RTX 40-series graphics boards will allegedly be quite power hungry with the top-of-the-range product featuring a thermal board power (TBP) of 450W and other rated for 420W and 300W, respectively. When it comes to power consumption, the information corroborates with earlier rumors indicating a major increase of TBP for Ada Lovelace family.
While power consumption of Nvidia's next-generation GeForce RTX 40-series products will increase compared to current-generation graphics cards, not everything is clear about pricing of the new boards. Kopite7kimi tells us not to expect GeForce RTX 4000 boards to feature lower MSRPs. Price is a particularly murky topic, keeping in mind higher production costs on TSMC's N5 process technology (or rather customized 4N) when compared to Samsung's 8LPP.
It is noteworthy that this time around Nvidia will use three different graphics processors for three initial cards. This might be a result of decent initial yields of Nvidia's Ada Lovelace GPUs at TSMC, or perhaps due to some changes in the company's internal chip design schedules. Anyhow, the gaps between the number of CUDA cores featured by the AD102, AD103 and AD104 GPUs might indicate that Nvidia will be very flexible with configurations for refresh (Ti-branded or Super-branded products).
Of course, Nvidia typically does not comment on specifications of unreleased products, so take the information with a grain of salt.
All the rumors just haven't been adding up, to me...
What's with the huge gap between "4080" and "4090", core-wise?
And has it been addressed why AD103 is assumed to be desktop, when the "03" has been reserved for mobile since at least the 900-series?
Seems much more likely to me that the AD102 would be both the 4090 and 4080, at 450W and 420W respectively. AD103 would be a mobile chip. AD104 would be a 4070.
Doesn't Nvidia usually chooses prices much closer to release (as in: day of the announcement) ?
Sorry for so many question marks in this post. :LOL:
You'll need at least a 1000W upwards PSU from the get go.
Update: I saw this on Gamers Nexus' YouTube channel. In relation to the increased power demand these new cards will have. (Video link should work in forum view.)
Room for 4080 Ti, 4080 Super, etc, which will be an in between card of some sort. Likely less memory and a slightly crippled version of the 4090 GPU. As usual Nvidia will see what the competition is up to and if there is a price point they can match, they will make a SKU that fits in logically.
There is no 103 chip that I can find, 100, 102, 104, and 106 and 107 in recent times. In the past 119, 117 were also common numbers.
If they really are doing a completely separate 103 chip, that would also explain the gap, it would be a smaller chip with the 4080 at the top. Not sure why the 4070 would then drop a further chip and not just be a 103-275 vs a 103-300. It could be they plan to have some overlap and use chips from multiple lines to make particular models. Wouldn't be the first time.
Pricing has to be done a little in advance so that they can pay import duties and the like.
