Uneven Resistance and Lack of Headroom: Why 12V-2x6s Fail

Analysis, Graphics | | Jan Olšan

No, the melting power connectors issue on GeForce cards is not solved as Nvidia claimed ahead of the new generation’s launch. There’s fresh GeForce RTX 4090 cases happening literally as we speak, and the risk seems even greater with Blackwell GPUs. The 12VHPWR (or 12V-2×6 now) connector has not just one but multiple flaws due to which it might never be truly reliable. Perhaps it would be best if it was discontinued in its current form.

Nvidia boosts RTX Video Super Resolution performance, adds HDR

Graphics, News | | Jan Olšan

When Nvidia unveiled GeForce RTX 5000 graphics in January, various new features were presented (though not all of them are exclusive to these new GPUs), most notably DLSS 4 able to generate more interpolated frames. We’ve devoted a separate article to Blackwell’s features, but now that the GPUs have started selling (albeit in limited quantities), we see that that are some additional new features that have flown under-the-radar before.

RDNA 3 refresh? Affordable Radeon RX 7650 GRE launched in China

Graphics, News | | Jan Olšan

Instead of the much awaited RDNA4 GPUs, AMD has introduced a new graphics card belonging to the RX 7000 generation. However, this card is likely to remain relevant even after the new generation arrives, serving as a more affordable option below the RX 9000 series. For now, this model is Chinese market exclusive, but that might change – the RX 7900 GRE, which was initially a China-exclusive, eventually made its way to other markets as well.

Tweaking Asus ROG Astral RTX 5080: Cut the Noise and Power Draw

Extra tests, Graphics | | Adam Vágner

Last week, we took a look at the Asus ROG Astral GeForce RTX 5080 OC Edition. It has a powerful cooler, but by default, the fan control pushes speeds high, and card is anything but quiet. So, I also measured how the card’s behavior changes when lowering fan speeds, how different power limit settings affect performance, and what the OC scanner does to the clock speed/voltage curve and how that impacts performance.

Gigabyte GeForce RTX 5080 Gaming OC Review: The Sweet Spot

Extra tests, Graphics | | Adam Vágner

At first glance, the Gigabyte GeForce RTX 5080 Gaming OC isn’t striking in terms of flashy design or vibrant lighting. It’s neither the cheapest nor the most expensive model. In a standard setup, the lighting is subtle, but the backlit fans stand out more when mounted vertically. The real advantage, though, is its oversized cooler and well-tuned fan control, allowing it to outperform even pricier competitors in terms of overall performance.

Some GeForce RTX 5090 fight melty connectors with thermal pads

Graphics, News | | Jan Olšan

Since GeForce RTX 4000, Nvidia graphics cards (fortunately just the highest models) have been facing issues with overheating and melting 12+4-pin power connectors. Newer models use the 12V-2×6 connector, which is designed to avoid improper attaching, and we recently discussed additional measures from Zotac. It seems that some of the freshly released graphics cards use another protective measure, addressing the root thermal issue.

Extra tests, Graphics | | Adam Vágner

With the new generation of GeForce GPUs, Asus is introducing the new ROG Astral series. Positioned at the top of Asus’s lineup, it inherits high-end features from previous ROG Strix models, including a dual BIOS, system fan control, a robust design, factory overclocking, and a large, top-notch cooler. It doesn’t just come with three but a total of four fans. However, this premium package comes at a significant price. Read more “Asus ROG Astral GeForce RTX 5080 OC Ed.: Brutalism in PC” »

Nvidia GeForce RTX 5080 FE Review: More Performance, Same Price

Extra tests, Graphics | | Adam Vágner

The GeForce RTX 5080 series gaming graphics cards go on sale today, and simultaneously, we can now publish performance test results. The biggest improvement over the last generation is an interesting performance boost in the most demanding titles at 4K and support for new standards and technologies. The edge is especially gained in demanding ray tracing scenarios, and vice versa. Read more “Nvidia GeForce RTX 5080 FE Review: More Performance, Same Price” »

Nvidia GeForce RTX 5090 FE review: Next-Level Gaming

Extra tests, Graphics | | Adam Vágner

Today ends the information embargo on tests of Nvidia’s top-tier GeForce RTX 5090 Founders Edition graphics card. It delivers extreme performance but at the cost of unprecedented power consumption and the highest price yet. Even so, it is expected to attract immense interest from gamers and professionals for its 32 GB of memory and exceptional application performance.

Nvidia GeForce RTX 5090 FE unboxing: Ultimate Design

Graphics, Preview | | Adam Vágner

Performance testing is still under an information embargo, but today we can unpack the box, look at its contents and introduce the card in detail. and take a closer look at the card in detail. The Founders Edition design is unlike anything we’ve seen before in graphics cards. The design and craftsmanship are precise, and when you look at the dimensions of its dual-slot cooler, it’s hard to believe it can cool the nearly 600W GeForce RTX 5090.

DisplayPort 2.1b introduced. New GeForce GPUs already have it

Graphics, Monitors, News | | Jan Olšan

A new version of the HDMI interface, HDMI 2.2 with new Ultra96-class cables was announced at CES. VESA’s competing DisplayPort standard is also getting an update, perhaps as a reaction to the new HDMI. It’s a minor upgrade though, with its label DisplayPort 2.1b indicating smaller changes compared to the previous new version 2.1a. This standard will be the first 2.x version available on Nvidia graphics cards. Read more “DisplayPort 2.1b introduced. New GeForce GPUs already have it” »

Radeon RX 9000 MIA? What we learned (not) about RDNA 4 at CES

Graphics, News | | Jan Olšan

AMD revealed a lineup of new CPUs for 2025 during CES keynote, but not graphics cards. Although the new RDNA 4 graphics cards were believed to target CES reveal, the Radeon RX 9070 and RX 9070 XT were not discussed. It seems out that the new cards were supposed to have just a “preview” at CES 2025. They were almost glossed over in the keynote, but outside of the video presentation, some information on the new cards was shared. Read more “Radeon RX 9000 MIA?

Cheaper Radeon RX 9070 has 16GB memory too. And 8pin power

Graphics, News | | Jan Olšan

AMD’s new graphics card, the Radeon RX 9070 XT, is coming this month. Chinese sources say it will have a 260–270W TDP and clock speeds of around 2.8GHz base and up to 3.0–3.1GHz in boost. Recently, more details of it came together, as well as the first news on the cheaper Radeon RX 9070 “non-XT” version. The latter was expected to have its memory stripped down to 12 GB and accordingly lower emory bandwidth. But things may be better. Read more “Cheaper Radeon RX 9070 has 16GB memory too.
