Sapphire RX 7600 XT Pulse or the cheapest 16 GB graphics card

Methodology: temperature tests

The cheaper of the pair of Radeons with the Navi 32 GPU is priced closest to the GeForce RTX 4060 Ti. Although you’ll pay a bit more for the RX 7700 XT, these graphics cards often have a significant performance edge, even attacking the RTX 4070. In this comparison, the RX 7700 XT with ray-tracing is already noticeably behind, and the Radeon’s efficiency is a notch weaker, but the price-performance ratio is often still better. And this is also true for the Sapphire Pure version in white.

Methodology: temperature tests

We’re also bringing you temperature tests. You are at HWCooling after all. However, in order to make it sensible at all to monitor temperatures on critical components not only of the graphics card, but anything in the computer, it is important to simulate a real computer case environment with healthy air circulation. The overall behavior of the graphics card as such then follows from this. In many cases, an open bench-table is inappropriate and results can be distorted. Therefore, during all, not only heat tests, but also measurement of consumption or course of graphics core frequencies, we use a wind tunnel with equilibrium flow.

Two Noctua NF-S12A fans are at the inlet and the same number is on the exhaust.When testing various system cooling configurations, this proved to be the most effective solution. The fans are always set to 5 V and the speed corresponds to approx. 550 rpm. The stability of the inlet air is properly controlled during the tests, the temperature being between 21 and 21.3 °C at a humidity of ±40 %.

We read the temperature from the internal sensors via GPU-Z. This small, single-purpose application also allows you to record samples from sensors in a table. From the table, it is then easy to create line graphs with waveforms or the average value into bar graphs. We will not use the thermal camera very much here, as most graphics cards have a backplate, which makes it impossible to measure the PCB heating. The key for the heating graphs will be the temperature reading by internal sensors, according to which, after all, the GPU frequency control also takes place. It will always be the heating of the graphics core, and if the sensors are also on VRAM and VRM, we will extract these values into the article as well.

Welcome, Adam! 18 years of experience in graphics card testing

Join us in welcoming Adam Vágner on board HWC today. Of the authors I know, he’s the most experienced with graphics cards. That’s what he’ll be covering. Thus, graphics card testing will be taken over by a tester who’s been doing it for a long time (and intensively). This is the approach we pride ourselves on and will continue to do so. There are plenty of “experts in everything”, but true specialists are slowly disappearing from the map. Read more “Welcome, Adam! 18 years of experience in graphics card testing” »

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

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?

Gigabyte RX 7900 GRE Gaming OC 16G in test of 30 graphics cards

The most “lightweight” AMD Navi 31 (XL) GPU, the slowest memory subsystem, but also the lowest price. That’s the RX 7900 GRE compared to the RX 7900 XT. This Radeon is also noticeably cheaper compared to the RTX 4070 Super, although the GeForce’s power efficiency is more favorable. The gaming performance of the RX 7900 GRE (RTX 4070S), meanwhile, is comparable. That is, as long as you won’t miss ray-tracing graphics.
