Many are already aware that the heating of GDDR6X memory in Nvidia’s top-end GeForce RTX 30 graphics cards can be reduced by installing copper thermal pads instead of standard ones. However, as it turned out, there is another solution – less laborious and more elegant from a purely aesthetic point of view. A copper plate for memory chips eliminates the need to install gaskets on each individual chip, while the cooling efficiency of such a solution is quite satisfactory.
The sale of copper plates in the United States is handled by a resource with the speaking name CoolMyGPU. The range includes various options for both the top models GeForce RTX 3080 and RTX 3090, and for the “popular Ampere” – GeForce RTX 3060, RTX 3060 Ti and RTX 3070, although they use less heat-prone GDDR6 memory.
One of the bloggers shared his own experience of using a copper plate on YouTube using the GeForce RTX 3080 as an example. It turned out that temperatures dropped by about 20%. Moreover, since the plate partially contacts the GPU frame, its temperature also decreases. The results are:
Cyberpunk 2077. GPU and memory temperatures up to -78°C and 88°C, after – 75°C and 70°C;
Mining Ehtereum. GPU and memory temperatures up to -65°C and 94°C, after – 58°C and 75°C;
OctaneBench. GPU and memory temperatures up to -78°C and 92°C, after – 78°C and 76°C.
In general, the copper plate works, but it must be understood that any intervention in the cooling system of the video card automatically voids the user’s warranty. As for the price of a copper plate, it is 30-60 dollars, depending on the model of the video card and the presence or absence of thermal paste in the kit.
The first PC based on AMD Ryzen 8000 processors has been introduced. The Minisforum V3 tablet will be very large
Despite the fact that there are clearly at least a few months left before the official announcement of Ryzen 8000 processors, Minisforum has already presented the first product based on such CPUs.
We are talking about a tablet, which is currently called Minisforum V3, but this is hardly the final name. The device will be based on the as-yet unnamed AMD Ryzen 8000 hybrid processor from the Hawk Point line. So far, all that is known about it is that its TDP will be 22-28 W, that is, it will be a model of the Ryzen 8000U line.
It is known about Hawk Point processors that these will be updated Phoenix models. They will carry the same Zen 4 cores, but the GPU will be based on the updated RDNA 3.5 architecture. In addition, the new APUs will have an XDNA block for working with AI.
Returning to the tablet, Minisforum is already talking about DDR5-6400 memory, two USB4 ports, an SD card slot, Wi-Fi 6E and Bluetooth 5.2. The tablet will also offer a huge 14-inch screen with a frame rate of 165 Hz and QHD+ resolution, four speakers, a fingerprint scanner, a 5 MP camera, stylus support and a battery with a capacity of more than 50 Wh.
Considering that the current Ryzen 7000U has a very powerful iGPU, the new processors should be even faster in this regard, meaning such a tablet can also be used for games.
Intel’s recent statement was misinterpreted. There will still be no full-fledged Meteor Lake-S desktop processors
Intel seems to have decided to confuse the public with its plans for the desktop processor segment. It turns out that there will still be no full-fledged desktop models of Meteor Lake-S.
Yes, Intel executive vice president and general manager of the client computing group Michelle Johnston Holthaus said just the day before yesterday that such CPUs would be released in 2024, which raised questions about three lines at once in one year. However, it now turns out that Holthaus did not actually mean the desktop segment in the form in which it is usually understood. Meteor Lake processors will indeed appear in desktop PCs, but this does not mean that such CPUs can be purchased separately and assembled into a computer based on them. In fact, Meteor Lake-S in the desktop segment will only be available in all-in-one PCs.
Meteor Lake is a power-efficient architecture that will power innovative mobile and desktop designs, including desktop form factors such as All-in-One (AIO). We will share more details about the product in the future
Intel already has experience releasing core KB desktop processors, which were only available in mini-PCs. Apparently, it will be the same story with Meteor Lake-S. Moreover, it is likely that technically these processors will completely copy mobile versions, except that the TDP may be higher.
That is, in 2024 we will have only two desktop lines: Raptor Lake Refresh, which will be released in October of this year, and then Arrow Lake-S sometime next year.
The GeForce RTX 5090 will not repeat the fate of the fire-hazardous RTX 4090. Tests of the 12V-2×6 power connector showed that it works even when connected incompletely
Back in July, we learned that Nvidia was working on a replacement for the fire-hazardous 12VHPWR connector. And now the first tests of the 12V-2×6 connector have appeared on the Internet, which should replace the 12VHPWR.
The authors of the HardwareBusters channel visited the laboratory of Linewell, which produces power cables, including for video card manufacturers.
Linewell tested the cable with the new connector, and tested it in a format that simulated the most common cause of 12VHPWR melting. At first, Linewell specialists tested it in normal mode for almost an hour, and the connector only heated up to 46.5 degrees. Then the cable was not connected completely, which usually leads to melting, and a power of more than 640 W was applied to it, that is, exceeding the established limit of 600 W. The connector passed the test, heating up to only 41 degrees.
