Bloomberg’s Mark Gurman told the news about future Mac minis with M2 and M2 Pro chips. He told about it in the Power On newsletter. According to the journalist, Apple was working on a Mac mini with an M1 Pro processor, but now this is clearly irrelevant. It was planned to be released at the end of last year or at the beginning of this.
Instead, according to the expert, models with M2 and M2 Pro processors are expected. However, their design will remain the same. The new Mac mini, codenamed J473, will feature the M2 chip. The version with the M2 Pro received the code J474. The source notes that Apple does not plan to release Mac mini with M2 Max or Ultra chips, most likely they will be kept for Mac Pro.
As for other models with M2 chips, Gurman believes that the Mac Studio may be a short-lived product, since it is positioned for the same audience as the Mac Pro. Also in the fall, the MacBook Pro is expected to appear with M2 Pro and M2 Max processors.
Previously, Gurman reported that Macbook Air will only appear in old colors.
For the GeForce RTX 4090, a power supply with a capacity of up to 1200 W is recommended
It’s no secret that Nvidia’s GeForce RTX 4090 graphics cards need powerful power supplies, but official recommendations from Nvidia partners vary.
Some manufacturers follow Nvidia’s recommendations for a standard 850W PSU, but many manufacturers list 1000W PSUs as recommended, some even insist on a 1200W PSU.
Asus recommends a 1000W PSU for its ROG Strix graphics card. Asus suggests this because the company assumes that users will be overclocking both the CPU and the GPU. The Gigabyte Aorus Master and Zotac AMP Extreme/Trinity RTX 4090 graphics cards have the same power supply recommendation of 1000W.
MSI, PNY, Galax, and Inno3D recommend an 850W PSU. However, Palit recommends using up to 1200W power supply for its RTX 4090 GameRock graphics card, which is the most stringent requirement among graphics card manufacturers today.
Today we already wrote that the GeForce RTX 4090 graphics card can consume more than 600 watts without any extreme overclocking. And when using the most powerful processors and overclocking, the power of the entire system will be much higher.
The first example that the GeForce RTX 4090 can consume over 600 watts. Card tested at Furmark
The GeForce RTX 4090 graphics card can indeed draw over 600W without any extreme overclocking.
The results of testing new items in Furmark have already appeared on the Web. In the msi-01 base test, the GPU frequency reached 3 GHz, and the power consumption was 426 W, but in the notorious Donut test, the frequency, although significantly lower (2.64 GHz), consumed the card almost 616 W! This test loads 3D cards much more heavily, which, as we can see, has a noticeable effect on power consumption.
In this case, the tests were carried out with a liquid cooler and, judging by the core frequency, in overclocking. Of course, without overclocking and in games, the consumption of the RTX 4090 will never reach what we see in the Donut test, but at the same time, such results mean that this is far from the limit for the adapter, and consumption during extreme overclocking can only be imagined .
Will the GeForce RTX 5090 and Radeon RX 8950 XT have such memory? Samsung to produce 36GHz GDDR7 memory
Samsung at the Samsung Tech Day 2022 event talked about the achievements and plans for its semiconductor business, at the same time touching on the topic of GDDR7 memory for future generations of video cards.
There are practically no details yet, we do not know when such memory will appear on the market, but Samsung indicated its frequency – 36 GHz!
Recall that GDDR6X memory currently runs at 21 GHz in some 3D cards. Of course, in all these cases we are talking about the effective frequency, but this applies to any such memory.
If we talk about top-end graphics cards with 384-bit bus, 36 GHz memory will provide 1.7 GB / s bandwidth! Probably, this will significantly speed up the new generation of 3D maps, even without taking into account new GPUs.
