DaVinci Resolve (Studio) video editing applications are highly optimized for hardware acceleration by GeForce RTX graphics cards. These can dramatically reduce the time of some tasks, turning hours into minutes or, for larger projects, days into hours. We’ll take a look at what exactly this is about in a two-part miniseries dedicated to streamlining work in Black Magic Studio video editors with NVIDIA Ada Lovelace GPUs.

In this article, we’ll take a look at some of the exclusive technologies that Nvidia GeForce RTX 4000 generation graphics cards can provide. We are going to explain the most significant new features currently supported by the GeForce graphics card ecosystem and perform tests showing how they affect performance in Cyberpunk 2077 with the new Phantom Liberty expansion. And we’ll also take a look at what they’re doing to image quality. Read more “Why want a GeForce RTX 4000? Nvidia DLSS 3.5 technology analysis”
We pay close attention to fan vibration in our tests, as it clearly indicates the mechanical qualities of the design. However, it is always good to have an idea why some fans vibrate more, others less, some not at all. And we will deal with this in more detail in this article, which is based on our own experience, but also on notes from fan developers. Can a cheap fan reach high speeds without vibration?

Yesterday we reported that x86 processors – at least those from Intel – will get Advanced Performance Extensions (APX), a major change in the programming of these CPUs. But Intel is also planning big changes to SIMD instructions with AVX10 technology, which will unify vector extensions whose subsets are now a mess, and should also address the problem of big.LITTLE processors. But this may in turn kill the true 512-bit SIMD capability of AVX-512. Read more “AVX10 seeks to replace AVX-512, will work on big.LITTLE CPUs”
Pressure here, pressure there. Omitting the adjective and not clearly specifying what type of pressure is being referred to can lead to all sorts of misunderstandings. Especially when in fan terminology, the word pressure is usually associated with static pressure. Not infrequently, however, dynamic or total pressure is meant. Complicated? Not really, you just need to be clear about what is being talked about and learn to read between the lines a bit. Read more “Dynamic pressure. How does it relate to other fan parameters?”
A trivial topic for some, for others something they didn’t understand as well as they should have. This is also indicated by various activities on discussion forums, including posts like “airflow is irrelevant, you mainly need high static pressure on a radiator”, which somewhat points to a connection of wrong contexts. In this article we will discuss very simply, with examples, what static pressure is and how to grasp it correctly. Read more “Totally simply: What is fan static pressure and what does it say?”
After Intel’s hybrid CPUs, AMD is preparing its own big.LITTLE scheme that uses a mix of Zen 4 cores and a new Zen 4c variant that will be used in servers but also in laptops. However Zen4c is and at the same time is not a little core. While having much smaller footprint, it is said to be fully architecturally equivalent to the large core, including (almost?) the same performance per 1 MHz. The only little thing about it is clock speed. Read more “big.LITTLE by AMD: Zen 4c has the same IPC as the big Zen 4”
ARM has been releasing a new generation of processor cores every year lately. This year will be no different (except for the Computex timing). ARM has unveiled a complete line of new architectures: a new Cortex-X4 “prime” big core for maximum single-threaded performance, a new medium Cortex-A720 core whose role is to provide multi-threaded performance (like Intel’s E-Core), and finally a new low-power Cortex-A520 little core.

We’re still in the process of finishing our review of the Radeon RX 7600 (the Pulse model by Sapphire), but we made a little preview, looking at a subset of tests that might go unnoticed in the final review: compute applications benchmarks. Why? The card seems to show better than typical performance gains in them. We’ve seen opinions stating that Navi 33 GPU bingst nothing new versus the Navi 23 chip, but these results say otherwise.

The headline may sound strange, but after reading the article it will make sense. After modifying a fan from unlit to lit, its noise level can change for a very simple reason. This is true even if the shape of the rotor or the operating speed has been maintained. As far as noise is concerned, a change by integrating ARGB LEDs does not always lead to a worse result. Still, it is important to know why any differences occur in the first place. Read more “Analysis: RGB LED implementation changes fan noise”
On edges of blades of some fans there are small notches forming a kind of teeth, typically on the trailing edges, closer to the motor. These elements serve to break up tonal peaks, and it’s curious that manufacturers are abandoning them rather than adding them. In some designs, however, such a modification can be seen as a backwards move; elsewhere it’s an understandable one. We have a few examples for you. Read more “Removing notches on fan blades? Sometimes a mistake”
November 3 saw the expected unveiling of a new generation of Radeon graphics cards from AMD with RDNA 3 architecture, a competitor to the GeForce RTX 4000, the already selling new GPU generation from Nvidia. In this article, we’ll discuss the chiplet design of the new 5nm AMD GPUs, the changes in architecture, and the new functionality and features that they bring. RDNA 3 has a lot of new stuff compared to the previous generation. Read more “AMD RDNA 3 details: architecture changes, AI acceleration, DP 2.1”
The Noctua NF-A12x25 fan may be the closest to perfection of the 120mm fans, but even the best things have their weaknesses. This will be no exception and there are elements of the NF-A12x25 that make sense to get into. And that this is true, Noctua will prove sooner or later in the next generation of 120 mm fans. But we’ll discuss the topic of what exactly to tweak, to do neater, right now.. Read more “HWCooling tips to optimize the Noctua NF-A12x25 fan”
Over time, we have tested ten motherboards with Intel B660 and Z690 chipsets in great detail. From more than 5000 different measurements, we can thus confidently deny some speculations that are usually spread on the Internet from the ignorance of the authors of articles or comments (in discussions). But this is natural. The less substantial the reviews are, the more fertile ground they create for various confusions. Read more “Analysis: What have we learned from motherboard tests”
Ryzen 7000 with Zen 4 architecture is the first AMD processor to support 512-bit AVX-512 vector instructions. We’ve already discussed their benefits (bigger or smaller) here. But the Zen 4 cores support another instruction set extension that used to be Intel’s pride and joy, and now the roles have reversed a bit: VNNI. It seems to bring huge performance improvements in a number of apps, despite the limited 256-bit width of Zen 4 SIMD units. Read more “Why is Zen 4 so fast in Topaz Labs AI apps? In fact it’s Intel’s doing”
