The latest GeForce RTX 4090 and RTX 4080 are compatible with older power supplies, but they don’t get DisplayPort 2.0 either

After a brief premiere during the official presentation, Nvidia updated the corporate website – now the database contains the latest GeForce RTX 4090 and RTX 4080 with all the characteristics. And they have something interesting.

The latest GeForce RTX 4090 and RTX 4080 are compatible with older power supplies, but they don't get DisplayPort 2.0 either

Perhaps most importantly, new 3D cards do not require a new power supply. Rumors attributed the GeForce RTX 40 to the transition to new PSUs with the same PCIe Gen 5 connector, but in fact both the GeForce RTX 4090 and the GeForce RTX 4080 are designed to use the old 8-pin connectors: three in the case of the GeForce RTX 4090 and GeForce RTX 3080 16 GB or two in the case of the GeForce RTX 4080 12 GB. However, all three models are also compatible with the new PSUs with a PCIe Gen 5 connector.

GeForce RTX 4090, according to official data, consumes 450 watts, GeForce RTX 4080 16 GB – 320 watts, GeForce RTX 4080 12 GB – 285 watts. Yes, in comparison with the models of the GeForce RTX 30 series, power consumption has increased, but not at all as dramatically as the rumors prophesied. It is possible that extreme versions of the RTX 4090 with a consumption of under 600 W will appear on the market, but these will be single models.

Nvidia lists the PSU power ratings for each of the three models – 850W, 750W, and 700W, respectively. Most custom gaming PCs will not need to be upgraded, as the requirements for the GeForce RTX 30 were not much lower.

Nvidia indicates that two of the three models received a three-slot cooling system, in the GeForce RTX 3080 12 GB everything is at the mercy of video card manufacturers (that is, it will not have a Founders Edition). But there will be many 4-slot models on the market (those that are not Founders Edition).

Another interesting point: all new items are equipped with HDMI 2.1a ports (HDR video output is supported at 4K resolution and 120 Hz), but the DisplayPort specification is only 1.4a.

In China you can already buy the GeForce RTX 4090

The GeForce RTX 4090 graphics cards have gone on sale, although there are still two weeks before the official launch.

Of course, we are not talking about mass sales around the world. The Gigabyte card has been acquired by at least one user in Hong Kong. Unfortunately, neither the seller, nor the price, nor additional details of the transaction are known.

But on the other hand, we can see the card itself in live photos, and at the same time once again make sure how huge the new Nvidia product is.

Unfortunately, you should not expect any test results from the happy owner, since Nvidia has not yet released the required driver. It will become available to everyone only on October 12, when official sales start.

Ryzen 7000s are very powerful but very hot Finally published

Literally, the ban on publishing reviews of the new Ryzen 7000 processors has just been lifted, so we can get acquainted with such materials.

Ryzen 7000s are very powerful, but very hot.  Finally published full reviews of new processors

For evaluation, we took reviews of all four new CPUs from our colleagues from TechPowerUp.

As befits a large review, the authors took a large number of applications for testing. However, if we talk about modern CPUs with a large number of cores, and especially about flagship models, potential buyers should pay attention to those applications that are important for each of them personally.

If we sum up some general results, then everything depends on the specific CPU.

The Ryzen 9 7950X is by far the highest performing non-HEDT consumer processor in the industry. In almost all applications, it shows the best result and somewhere it can lose to some other new product from AMD due to the lack of optimization for a large number of cores. The Ryzen 9 7950X is on average 25% faster than the Ryzen 9 5950X and 15% faster than the Core i9-12900K. However, in some applications, the difference can reach 30-50%.

The 12-core Ryzen 9 7900X is about 6% faster than the Core i9-12900K and 15% faster than the Core i7-12700K. The eight-core Ryzen 7 7700X is 20% faster than its predecessor (Ryzen 7 5800X), while in a number of tasks the new product manages to bypass even the Core i9-12900K, although on average, of course, the latter is faster. As for the popular six-core Ryzen 5 7600X, it is 25% faster than its predecessor and is often able to compete with the Ryzen 9 5900X, which has twice as many cores! On average, the results are certainly not so impressive, but for those who use certain applications, the Ryzen 5 7600X can be almost a miracle.

In games, as always, everything primarily depends on the video card, but in those modes where the influence of the CPU is somehow noticeable, AMD’s new products show themselves perfectly, bypassing even the gaming Ryzen 7 5800X3D.

However, there is also a fly in the ointment. All this huge performance gain was not in vain, and the Ryzen 7000 added a significant amount to power consumption.

Under heavy load, the Ryzen 9 7950X draws around 235W, versus just 118W for the Ryzen 9 5950X. And even the six-core Ryzen 5 7600X consumes 100 watts. True, this is a lot only against the background of the previous generation Ryzen, since the same Core i9-12900K requires more than 250 watts.

At the same time, if we talk about the average consumption in different applications, everything is better here: only 125 W for the Ryzen 9 7950X, which is completely uncritical and still less than the Core i9-12900K.

New AMD processors heat up accordingly. In the same Blender application, the new flagship heats up to 94 degrees, and this is using the powerful Noctua NH-U14S cooler. And the problem is that even the Ryzen 5 7600X heats up to 88 degrees, and the Ryzen 7 7700X does not lag behind the flagship. Again, in games and more gentle programs, the heating is much less: within 70 degrees. And it’s also worth repeating that this is all a lot compared to the Ryzen 5000, because Intel Alder Lake shows no less heat.

Of course, you need to remember that tomorrow Intel will introduce the new Raptor Lake processors, and it is with them that the Ryzen 7000 will compete. which one will compete is not yet clear. And taking into account the preserved technical process, increased frequencies and an increased number of cores, it is likely to heat up and consume new Intel CPUs even more.

Nvidia has created a “video card” with 120 GB of memory. Accelerator H100 will receive a new modification

The Nvidia H100 accelerator in the modification with the PCIe interface can have 120 GB of memory.

Nvidia has created a

So far, Nvidia has not announced such a version, and it is not certain that there will be at least some kind of announcement, since in general the H100 model debuted back in March. But the solution hits the market only now and, apparently, by this time the company has prepared a new version.

Nvidia has created a

Initially, we recall that the H100 was presented in versions with PCIe and SMX with a different number of CUDA cores, but with the same amount of HBM2e memory of 80 GB. The new version will differ from the originally announced one only in memory, that is, the novelty has the same 16,896 CUDA cores. True, since this is HBM memory, an increase in volume also leads to an increase in throughput: from 2 to 3 TB / s. The SMX version has a throughput of 3.35 TB/s due to interface features.

The Nvidia H100 is the first Hopper generation solution. This is a line of accelerators specially designed for computing, and there are no gaming analogues for such cards.
