Sapphire NITRO+ Radeon RX 6700 XT Review: Bigger, Faster, Cooler

Manufacturer: SAPPHIRE Sapphire NITRO+ Radeon RX 6700 XT Review: Bigger, Faster, Cooler

Our launch coverage of the Radeon RX 6700 XT continues in the hours after the review embargo lift, as multiple vendors are launching their own versions of the new 40 CU RDNA 2 GPU from AMD. Sapphire is, naturally, one of these AIB partners, and they have another of their big, quiet, and factory overclocked NITRO+ cards for us today.

As we have discussed, the RX 6700 XT is based on new (much smaller) silicon, and is the first of AMD’s RDNA 2 GPUs with a 192-bit memory bus and 96 MB of Infinity Cache – down from 256-bit and 128 MB, respectively, with the RX 6800 cards. The 192-bit memory bus also means a reduction in total VRAM (yes, the two are related), but AMD chose to go with 12GB of GDDR6 rather than 6GB – the same decision NVIDIA made with their RTX 3060.

For a bit more about this new GPU check out our AMD reference card review. Now, let’s check out the NITRO+ card.

The Sapphire NITRO+ Card

This card is every bit as large as the NITRO+ RX 6800 we reviewed back in December, and you are certainly getting a more robust thermal solution with Sapphire’s NITRO+ compared to a reference design.

We detailed the features of this new Tri-X cooling solution in the NITRO+ 6800 review (exclusive to Sapphire’s RX 6000 cards), but here are some of the advantages (quoting Sapphire):

  • New Hybrid Fan Blade – The new Hybrid Fan Blade improved the GPU temperature by 3.4 C and memory temperature by 3 C over the last gen NITRO+ RX 5700 XT fan blade design
  • WAVE Fin – The new wave fin design reduces the friction when the wind goes intot he find module so as to reduce the wind cut noise
  • V Shape Fin Design – The V shape find design on top of the GPU accelerates and centralizes the air flow around the GPU to dissipate the heat efficiently
  • New Memory/VRM Cooling – New stand-alone memory/VRM cooling module does not just cool the memory and MOSFET, but also the chokes

The card measures 310.05 mm in length, 130.75 mm in height, and is 51.4 mm wide – occupying 2.5 slots. There are the standard 8-pin + 6-pin PCIe power connectors, and a dual-position BIOS switch for fan profile selection.

I didn’t get into RGB lighting with this one, but it’s the same addressable system as the NITRO+ RX 6800 we looked at previously, so if you like ARGB stuff you’ll like this.

TRIXX Software

It wouldn’t be a Sapphire review if we didn’t at least mention TriXX software, and in particular the utility’s easy to use resolution scaling feature. Simply choose a scaling percentage (it defaults to 85%), toggle some new in-game resolutions, and decide if you want to enable AMD’s Radeon Image Sharpening.

It’s as simple as applying the setting and then manually selecting your new resolution in any game. And the result is better performance, with virtually no downside at a high quality (85%) setting like this. It’s not DLSS, but it works perfectly and you’ll be hard pressed to notice that it’s on.

Performance Benchmarks

Revisiting some of the benchmarks from our reference card review (same test setup and driver version), you’ll notice that this factory overclocked card does in fact offer better performance with zero user intervention. I left the BIOS switch in its default position and here are the results:

Far Cry 5
Sapphire NITRO+ Radeon RX 6700 XT Review: Bigger, Faster, Cooler - Graphics Cards 28

Far Cry 5 at 3840×2160/Ultra/HD Textures produced the best showing for the RX 6700 XT in the reference review, and here the NITRO+ takes it up another FPS. Not a big difference, obviously, but better. The next game shows a bigger jump.

Tom Clancy’s The Division 2
Sapphire NITRO+ Radeon RX 6700 XT Review: Bigger, Faster, Cooler - Graphics Cards 29

This was such an impressive jump from my earlier benchmarks using the reference card that I started looking for an error – until I remembered that Division 2 is the worst-case benchmark for heat that I use. To clarify, the menu for the game runs the GPU at full speed, and the heat just builds and builds between benchmark runs. I suspect that the superior thermals from this NITRO+ aided in the higher average FPS result we see here

The next two games are backing to showing only single FPS improvements, leaving The Division 2 as the outlier in this review.

Power and Thermals

Higher clocks on the same process means more power consumption, but the difference here is only 24W so it shouldn’t affect your PSU selection.

A system that never even reached 400W during any of my testing is just fine with me. Sapphire recommends a 650W power supply with this card, but I think you could get away with a quality 550W unit (but don’t blame me if something goes horribly wrong).

Using GPUZ I monitored GPU thermals for a couple of benchmark runs, pitting our AMD reference sample against this Sapphire NITRO+ card. This software does not log memory temps with this GPU, so I had to content myself with the following chart:

Sapphire NITRO+ Radeon RX 6700 XT Review: Bigger, Faster, Cooler - Graphics Cards 33

This is a big improvement. The reference card hit approximately 78 C GPU / 94 C hot spot, while the NITRO+ brought this down to 59 C GPU / 83 C hot spot under identical conditions.

As to noise, in use I have found these NITRO+ cards to be very, very quiet under load – to the extent that they can’t be heard over the CPU cooler, and therefore can’t be tested for sound pressure level properly without a passive CPU cooling setup (which I don’t currently have). We are talking about noise levels under 35 dBA in my shorter benchmark runs, though of course fans can be ramped up manually into the more audible range.

Pricing and Conclusion

The expected pricing from Sapphire is $579 for this NITRO+ RX 6700 XT, but that price doesn’t indicate what the card will actually sell for any more than AMD’s $479 list price for the reference card. And if the price seems high, then you really don’t want to know what RX 6800 cards sell for right now.

Sapphire NITRO+ Radeon RX 6700 XT Review: Bigger, Faster, Cooler - Graphics Cards 34

My conclusion is simple: Sapphire’s NITRO+ RX 6700 XT is a cool running, quiet graphics card with better performance out of the box compared to AMD’s reference design. Sure, the performance gains are not massive, but we didn’t get into any additional overclocking, either (and this cooler certainly leaves some thermal headroom).

Value arguments are out the window in 2020-2021, so I’ll just say that if you can find this for an appropriate price for your needs, you won’t be disappointed. It’s a rock solid option from a reliable vendor.

    Sapphire Nitro cards are always some of AMD cards you can get it though I was kinda hoping they would make the 6700XT version of their Nitro a dual fan card. The cooling performance is definitely there but thats not necessarily due to the number of fans and I think a dual fan design fits the x700 segment better.
