Intel Core i9-12900K lights up with Gigabyte Z690 Tachyon motherboard and DDR5-8000 memory

An insider who published the results of the test of the Core i9-12900K processor in the Cinebench R23 test, presented screenshots of the stand with the same CPU. But here the attention is drawn not so much by the processor as by the RAM. With Core i9-12900K, DDR-6200 memory was used, but overclocked: the frequency was raised to 4004 MHz, and the speed – 8008 MT / s. The delays CL, tRDC, tRP, tRAS and tRC were 50-50-50-125-150.

The screenshots clearly show that the memory supports several XMP-6200 profiles and at least one XMP-6400. The maximum voltage reaches 1.5 V, which is 400 mV higher than the standard for DDR4-4800.

Officially, Intel Core 12 (Alder Lake) processors support DDR4-3200 and DDR5-4800 memory modules, however, as you can see, the platform allows memory overclocking. Another question is to what extent such overclocking will be justified.

What’s missing in the new MacBook Pros yet? Support for external video cards did not appear here either.

Published

on

As you know, the first Apple laptops on the SoC M1 do not support external video cards. We now know this is true for the new M1 Pro and M1 Max-based MacBook Pros as well.

Despite the presence of Thinderbolt 4 ports, Apple’s new laptops lack support for external graphics cards, and the company has yet to explain this limitation. Perhaps it is primarily due to the Apple Silicon architecture.

Of course, we have already seen that, at least for the M1 Max, using an external video card may be pointless, but we will not mention the M1 Pro and the original M1.

Whether support for external video cards will appear in future Apple laptops with its own platforms is anyone’s guess. It is possible that GPU performance in Apple Silicon will grow at such a rate that discrete adapters will really not be useful in the corresponding bundles.

Recall also that the new MacBook Pro also lacks support for the latest standards for SD memory cards.

Finally, Windows 11 users have the full power of Ryzen processors. Both performance issues have been resolved

Published

AMD and Microsoft have finally resolved both Ryzen and Epyc CPU performance issues when running Windows 11.

Microsoft has already released the patch in the Insider Build, now it’s available to everyone. Recall that it solves the problem of high latency in the L3 cache.

AMD, in turn, has released a patch that solves the problem of UEFI CPPC2 with incorrect work of the task scheduler for processor cores.

In the case of the first patch, you need to install a Windows update, but the second one needs to be downloaded from the AMD website yourself. More precisely, you do not need to download a patch, but a fresh driver for the motherboard chipset – the patch is part of it.

Top mobile graphics cards can’t handle the Apple M1 Max SoC? The GPU tests of the new MacBook Pro platform appeared

Published

on

The graphics core of the Apple M1 Max SoC is characterized by a performance of 10.4 TFLOPS, which puts it on a par with the GPU in the PlayStation 5 or, for example, with the GeForce RTX 2080. True, the performance in TFLOPS depends solely on the number of ALUs in the GPU and the frequency, so that this indicator has little to do with real performance. But now we can finally appreciate the real power of the M1 Max.

Not in games yet, but in a benchmark, but this is already something. In this case, we are talking about the GFXBench test software, and the competitors for the new Apple platform were the Apple M1 SoC, the Radeon RX 6800M and the mobile GeForce RTX 3080. The last two cards roughly match the performance of the desktop Radeon RX 6700 XT and GeForce RTX 3070, respectively.

As you can see, the GPU in the M1 Max is often faster than both very powerful discrete graphics cards, which is impressive. More precisely, out of nine tests, M1 Max was the clear leader in four and outperformed AMD and Nvidia cards by a narrow margin in another. In addition, of the remaining four tests, the Apple solution lost insignificantly, and in two more it was at the level of the Radeon card. In fact, only one test showed a very large gap between the M1 Max and discrete graphics cards.

As for the comparison with the M1, where the GPU cores are four times less, here the gain is always very large, although sometimes it is still less than twofold.

Of course, you need to wait for tests in games to put an end to this confrontation, but here it is worth understanding two aspects. First, the powerful GPU in the MacBook Pro isn’t needed for gaming. Secondly, we are still talking about a single-chip system with a very low power consumption by the standards of a CPU or GPU, which at the same time is able to compete and surpass full-fledged CPUs and GPUs.
