“All” graphics cards in in-depth coil whine analysis

Extra tests, Graphics | | Ľubomír Samák

The number of graphics cards tested over the recent period has reached a number after which we can pause a bit and specifically focus on the noise level of their coils. The latter has always been recorded in standard measurements, but in large tests with lots of other information, this unique data was getting lost. That is why it will now, within the scope of this article, be limited to these only. So which of the modern graphics cards has the quieter coils?

Situation 3: CS:GO (2160p)

Thanks to a reader nicknamed “the patient“, you now also have spectrograms with a noise level scale and a Y-axis label. These elements had to be added separately, in an external application, because they were not included in the cutouts (4–20 kHz) of the complete spectrograms (20 Hz–20 kHz).

AMD has started mass production of Zen 6. Only for Epycs for now?

News, Processors | | Jan Olšan

It’s been nearly two years since AMD’s Zen 5 architecture launched (in late July and early August 2024) and time is ripe for a successor—especially given how far competitors such as Qualcomm’s Snapdragon X2 Elite and Apple’s M5 have advanced in the meantime. AMD’s answer in the form of the Zen 6 architecture is now finally getting closer—the company has announced the ramp up of production, which could signal a launch later this year.

Advanced Shader Delivery on AMD: No more waiting for compilation

Graphics, News | | Jan Olšan

Gamers definitely know the experience: You want to launch a game, but it starts to compile shaders, which can take several minutes. The reason is that shaders have to be built from code specifically for your hardware. And the compilation must be repeated after every GPU driver update, so you can end up seeing this waiting screen quite frequently. But Windows is now getting an improvement that should largely eliminate this waiting. Read more “Advanced Shader Delivery on AMD: No more waiting for compilation” »

FSR 4.1 AI upscaling finally coming to older Radeon GPU users

Graphics, News | | Jan Olšan

When AMD launched the FSR4 AI-based upscaling technology for games last year, it was exclusively available for the new Radeon RX 9000 generation GPUs using the RDNA 4 architecture. This was despite the fact that a version using INT8 compute compatible with older GPUs had leaked out, apparently by accident. But owners of older Radeon cards are finally in luck now: FSR 4.1 is coming to RDNA 2 and RDNA 3 as well. Read more “FSR 4.1 AI upscaling finally coming to older Radeon GPU users” »

  1. So, there are now additionally spectrograms with the scale and the Y axis label (with the noise level) in the article. Thanks to “the patient” for adding it quickly. 🙂

  2. Pretty incomplete when PASSIVE (KalmX) GPU versions from Palit not included in such test..

    1. Yes, a Palit KalmX graphics card would have been great for a test, I agree. Unfortunately, we couldn’t get our hands on one. It’s similar to when people point out the absence of Thermalright products in our tests. Their availability in our CZ/SK market is quite limited, which makes them harder to source. Even though our magazine is localized into English, many companies still consider HWCooling as a “Slovak” medium with a smaller reach. That’s the reality. 🙂

  3. What I’m wondering is why the PWM fan peak doesn’t show up at all in the graphs? I’ve had a Zotac 5070 Ti, a KFA 5070 Ti, and an ASUS 5070 Ti, and all of them produced a strong peak between 13 kHz and 15 kHz as soon as the fans started spinning — sometimes even without any GPU load, just because the fans were running. On my current KFA 5070 Ti OneClick OC, that’s even around 35 dB near the card. Unfortunately, I have tinnitus, and frequencies like that trigger it badly, especially when they’re that “loud.” But in your charts, I don’t see those fan peaks at all — did you measure differently, or somehow filter them out?

    1. — „What I’m wondering is why the PWM fan peak doesn’t show up at all in the graphs?“

      Yeah, I reckon what you are missing is the results is not there due to the diversity of testing methodologies. Other people will test fans differently than we do. 🙂
