Asus ROG Strix RX 6700 XT OC – Design and Features
The ROG Strix RX 6700 XT OC is nothing if not high-end. It follows the same styling as the RX 6800 OC I reviewed back in December, which means that it not only looks good, but is also built as a tank. It is a design that uses heavy metal for an industrial gray tone color with eye-catching silver colors. Around the back, a solid metal plate completes the package.
This is also trimmed with a discreet style, but consists of black and two dark gray shades. As the front blends surfaces, it combines brushed aluminum, glossy stripes and sections with a smooth matte finish. The design is meant to fit seamlessly with ROG motherboards, and it works well, including the customizable RGB stripe along the side, which can also be disabled to complete the minimalist look.
Strix uses a triple fan cooling solution and is large and bulky. It takes 2.9 tracks in width and spans almost 13 inches, so this is not a GPU for space-constrained buildings. The whole package is quite heavy, but the frame is reinforced to prevent bending of the PCB. Still, without any support, it immediately sank into my system, so I would recommend buying an extra bracket to support it behind. The larger size allows Asus to design around thermals and acoustics, as well as add a pair of PWM fan heads for connection and control of additional fans.
When you return to cooling, the card is equipped with a trio of Asus Axial-tech fans. The center fan has two extra fins to increase the static pressure and force more air between the fins on the heating stack. They also have an opposite rotation scheme for more efficient airflow. The heat sink overlaps the PCB and Asus supports this with vents and outdoor air to better dissipate heat. Overall, the cooling solution here is nothing short of fantastic.
My selection reached a peak of 64C, but spent most of the time in games hovering between 59-60C. The card has a zero RPM mode, which leaves the fans off until it hits 60 degrees Celsius and then deactivates them again when they hit 55C. With such low temperatures, the fans never had to be loud and mixed in seamlessly with my suitcase fans. The card also has a dual BIOS with performance and quiet mode, but since it’s so quiet anyway, I see no need to move it out of the default performance setting.
Under the hood, the Strix has the same configuration as all the RX 6700 XT, but comes with a decent factory overclocking. That means you can look forward to 2560 stream processors and 40 computing devices, as well as 12 GB of GDDR6 memory on a 192-bit bus. However, as I describe in my review of the RX 6700 XT reference, the card also supports 96 MB Infinity Cache, which improves memory efficiency, and AMD claims performance more in line with the 256-bit GDDR6. Regardless, the memory speed is clocked at 16 Gbps.
Out of the box, the clock speeds are faster than the original, with the highest rated speeds hitting 2.62 GHz for Boost Clock and 2.55 GHz for Game Clock. The reference 6700 XT only guaranteed speeds of 2.58 GHz and 2.42 GHz, respectively. These are not giant potential customers, but should support some extra FPS in games when comparing apples to apples. Since each RX 6700 XT is capable of increasing speeds intelligently based on thermal and power constraints, and the threshold for thermal throttling is well above what each card actually hit, they each came pretty close with their true clock speeds. At the top, the ROG Strix reached 2.63 GHz and hovered around 2.58 GHz while playing. The reference card peaked a little higher even at 2.64 GHz and hovered around 2.5 GHz. So in general, ROG Strix used to hover around 80 MHz faster than stock.
Since this card is also built on the RDNA 2 architecture, you can also look forward to these benefits, including Smart Access Memory which can provide performance when used with a supported Ryzen processor. It also means hardware-level beam tracking (sense of any DLSS-like feature, unfortunately), improved performance per watt over AMD’s RX 5000 series and DirectX 12 Ultimate compatibility, as well as AMD’s FidelityFX image enhancements.
Like the reference RX 6700 XT, the card has three DisplayPort 1.4 outputs and a single HDMI 2.1. The card supports a maximum resolution of 7680×4320 on up to four monitors. HDCP is supported, as well as AV1 and VP9 decoding and H.264 and H.265 encoding and decoding.

Asus ROG Strix RX 6700 XT OC – Performance
I test graphics cards using a mix of synthetic and real game benchmarks. These tests are performed with ultra-settings, unless otherwise stated in the subtitle of each chart. Nvidia cards have been tested with DLSS enabled to better represent the situation players today will find themselves in when choosing one card over another with supported titles. Similarly, the reality in the video game industry today is that most games that support beam tracking also support DLSS, so balancing games is important and especially for users who are upgrading from a non-RT graphics card. However, it is worth remembering that DLSS upscales lower-resolution content, and that original resolution will ultimately provide the best image quality. At the time of writing, AMD has not released its response to DLSS, FidelityFX Super Resolution. When it does, future testing will factorize it.
Note: our system uses an Intel i9-9900K and does not support Smart Access Memory. Systems with this feature may outperform some titles, potentially closing the gap on the Nvidia RTX 3070.

Starting with synthetic, ROG Strix works very well. It tops the original RX 6700 XT in every test. These are score-based and not real, but provide a good indicator of where we can expect the card to land while playing against these comparison cards. Compared to the original, the Strix is 2% faster in Fire Strike Ultra and 1% faster in Unigine Heaven.
When it comes to radiation tracking, the story is much the same. Strix best AND in all, except Boundary synthetic where it just binds. These tests really show the difference between AMD and Nvidia’s raytracing solutions. Strix is 2% faster than the reference in both Port Royal and 3DMarks Ray Tracing Test.

Asus ROG Strix Radeon RX 6700 XT OC – Benchmarks for gaming
When it comes to gaming tests in real life, the results found in synthetic fabrics are carried out. The ROG Strix RX 6700 XT performs better than the reference card in almost all cases. Many of these differences are small, but come between 1-3 FPS and sometimes less. At 60+ FPS, the difference is imperceptible to my eye. The biggest wins come in 4K where it is on average 3% faster, but since most players will not play in this resolution with 6700 XT, that is a small point. At 1440p and 1080p, the card also leads by a range of 1-3% across these five games, giving an average of 1% improvement with each resolution.
For the extended test round, I decided to add RTX 3080 to the mix. The RX 6700 XT is not meant to compete with the RTX 3080, but given that it lists for almost $ 130 more than an entry-level RTX 3080 – if you find one on the MSRP – I thought that was a fitting comparison.
Starting at 1440p, the Strix comes 2% faster than AMD’s own version. Compared to the RTX 3070, it drops by a total of 17%, but since raytracing games have DLSS-enabled, it is important to consider the rasterization gap, which is only 8%. Against RTX 3080, the card delivers 39% less FPS overall and 27% less when beam tracking is removed from the assessment.
At 1080p, the Strix is on average 1% faster than the original RX 6700 XT. Against RTX 3070 it goes a little better and comes 12% slower in general, but with actually 3% faster in pure rasterization. Against RTX 3080, it is expected to lag behind with 29% slower overall and 18% slower in non-beam tracked games.
Looking at these results, two things are clear. First, the ROG Strix RX 6700 XT is the superior card of the reference RX 6700 XT. It’s objectively good for 1440p and 1080p games, as it should be at this price. Second, and more importantly, the results are so close that most players are unlikely to notice the performance, despite the relatively exorbitant price. It’s not bad: the performance gain is there, the improved temperatures, acoustics and appearance are there, but is any of it enough to justify charging $ 350 more for a 2% performance gain?
To be honest, if what you are looking for is performance, it does not make sense to buy this card at current prices. Other RX 6700 XTs, even those with custom triple fan coolers, are available for hundreds of dollars less. An RTX 3080, a card that offers far better performance and DLSS support, shows as low as $ 699 on the Newegg. If you find it.
Which is really rubbing. This card feels expensive because it can not be because it should be. Republic of Gamers products have long lived in the “prestige” category of PC components. They are well made, well supported and offer a combination of quality, features and style that has served its current pedigree. However, due to the current shortage, this card, along with a number of others from competing brands, is listed at prices so high that they make objectively good cards into objectively bad recommendations.
