A few weeks ago, I tested the classic black version of the Asus Prime GeForce RTX 5070. It stood out for its combination of very good thermals and acoustics and an attractive price. However, one of the fans was lower quality, making the card noisier than it should have been. I decided to retest it with the white version. The good news is that the fan issue didn\u2019t recur. As for overall noise levels, though, there’s still not much improvement.<\/p>\n

A detailed description of the new technologies brought by Nvidia\u2019s new graphics cards has been compiled by Jan Ol\u0161an in the article Blackwell: GeForce RTX 5000 architecture and innovations<\/a>. It introduces the individual graphics chips Nvidia is using in the new cards, the new GDDR7<\/strong> memory type, and also covers changes in cache memory, GPU compute units, updates to shaders and tensor cores, as well as improved compute units for ray tracing. The new generation of GeForce also brings support for new standards such as DisplayPort 2.1b<\/strong> and PCI Express 5.0<\/strong>.<\/p>\n

With the new generation of cards, DLSS capabilities are evolving as well. It now supports Multi Frame Generation<\/strong>, which allows the generation of up to three intermediate frames, and introduces Nvidia Reflex 2, the second generation of its latency-reduction technology. This includes Frame Warp<\/strong>, which adjusts object and camera motion in rendered frames based on the player’s most recent input device movement data received just before the already rendered frame is displayed. A more detailed explanation can be found in the aforementioned article.<\/p>\n

The GeForce RTX 5070 uses Nvidia\u2019s third GPU based on the Blackwell architecture. Internally labeled as the GB205, it comes with 6,144 CUDA cores, 192 texture units, and 80 ROPs. Unlike higher-end models that feature a 256-bit memory interface and 16 GB of VRAM, this GPU is limited to a 192-bit bus and therefore ships with 12 GB of memory. The RTX 5070 is currently the only desktop GeForce card utilizing this particular GPU.<\/p>\n

A detailed comparison of the RTX 5070\u2019s specifications with its closest relatives in the GeForce lineup is available in the table below. From now on, let\u2019s focus on the tested Asus model.<\/p>\n

Testing the Asus PRIME GeForce RTX 5070 White OC Edition 12GB GDDR7<\/h2>\n

(PRIME-RTX5070-O12G-WHITE)<\/h3>\n

Some time ago, we reviewed the same model in black<\/a>, which, with a starting price around 608 EUR, ranks among Asus\u2019s most affordable RTX 5070 cards. Slightly cheaper should be the non-overclocked version: the Prime GeForce RTX 5070 GDDR7 12GB. In practice, however, that\u2019s not the case in some markets, where limited availability means the OC version (Prime RTX 5070 O12G) can currently be found for less than the base 12G variant, which starts at 660 EUR.<\/p>\n

The only cheaper options are two Dual GeForce RTX 5070 variants, though they are not widely available yet. Above them sit the TUF GeForce RTX 5070 12GB OC Edition<\/a>, which we\u2019ve already tested, and two ROG Strix models.<\/p>\n

The white version of the Prime RTX 5070 sits above the Dual and black Prime versions in price. It currently sells for 697 EUR, so be prepared for a noticeable markup.<\/p>\n

\"\"<\/a><\/p>\n

The card comes factory overclocked. The advertised boost clock is increased from the reference 2512 MHz to 2557 MHz. Actual boost clocks will vary depending on load and power consumption. You\u2019ll find the GPU clock speed behavior under load in the sections with operating characteristics.<\/p>\n

It features dual BIOS support, labeled P mode and Q mode. The base specs such as clock speeds and power limits remain the same between the two; the main difference is in the fan curve. In both BIOS modes, the boost clock is increased to 2625 MHz, while memory stays at the standard 28 Gbps GDDR7.<\/p>\n

P mode is the default. Q mode can be enabled via a switch near the power connector. Below are GPU-Z screenshots showing P mode first, followed by Q mode settings.<\/p>\n

\"\"<\/a><\/p>\n

The power limit is the reference 250 W, with an adjustable range between 175\u2013300 W (\u201330% to +20%). In monitoring tools, the three fans are split into two controls: fan 1 covers the outer fans, and fan 2 controls the middle one.<\/p>\n

\"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a><\/p>\n

HWiNFO reads significantly more data from the card\u2019s monitoring sensors than GPU-Z. The sensors available in the current version can be seen in the screenshot below.<\/p>\n

\"\"<\/a><\/p>\n

Additional screenshots show Q mode BIOS settings. The only meaningful difference from P mode is a shallower fan curve, resulting in lower fan speeds under load.<\/p>\n

\"\"<\/a><\/p>\n

The BIOS version differs from the model we tested in May\u2014this one is two months newer. I\u2019d really like to know whether that\u2019s why fans now spin faster under load. But we\u2019ll get back to that.<\/p>\n

\"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a> \"\"<\/a><\/p>\n

The packaging continues the white theme. On the back, Asus highlights features and technologies used in the card. The cooling system includes a MaxContact base, a backplate with a flow-through design, and Axial-tech fans. Other durability-enhancing features include dual-ball bearing fans, a phase-change thermal pad, a reinforcing metal frame, and a stainless steel I\/O bracket. Its compact 2.5-slot cooler fits within the Prime ecosystem. Asus also promotes the GPU Tweak III software for monitoring, overclocking, and fan curve tuning. The rest of the box reiterates standard Nvidia features.<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a>\"\"<\/a><\/p>\n

The extent of the white theme is impressive. Virtually everything usually black is now white: the inner box, foam insert, leaflet envelope, cable tie, and even the PCIe and display port dust covers.<\/p>\n

\"\"<\/a><\/p>\n

In this context, the black power adapter sticks out like a sore thumb. Recoloring it would probably raise costs slightly. It\u2019s a standard adapter with two 8-pin connectors and one 16-pin (12V-2×6). A nice touch: an included reusable Velcro cable tie. You\u2019ll also find the usual set of leaflets and a quick start guide.<\/p>\n

\"\"<\/a><\/p>\n

We\u2019ll look at the card\u2019s detailed features in the next chapter.<\/p>\n
