Sapphire Pulse AMD Radeon RX 6800 OC Gaming 16GB GDDR6 Review

It is time for the first customized Radeon 6800 review, no not the XT, I meant that non-XT. In this review, we test the Sapphire Radeon RX 6800 NITRO+ based on a custom PCB, custom cooler, and increased clock frequencies. Do you need a silent 6800? Look no further, you found it. Based on a custom PCB, custom cooler, and increased clock frequencies. It has been a long wait for AMD and sure, us. When the first NAVI based graphics cards were launched, they became well respected.

The 5600 and 5700 series does offer some good performance. But during that launch everybody was already talking about one thing, where is Big Navi? It’s now November 2020 as we write this and here we are, the world completely changed. Next to everything COVID-19 related, in the world of graphics technology, a new dynamic was added, Raytracing. Or, I should say DirectX Raytracing (DX-R). NVIDIA was pioneering two years ago with their RTX 2000 series already, and AMD made the call to delay that for the original Navi GPU. As the graphics landscape changed somewhere done the line, so this the roadmap for AMD change. Microsoft and Sony consoles embedded with AMD technology revealed that Raytracing was going to be supported. And that did set the trend for the desktop graphics card we see announced. AMD announced three graphics cards based on Big Navi, they all hold the very same GPU, just binned and somewhat ‘weakened’. Interesting to learn is that the new GPUs are fabricated on an optimized 7nm node derived from TSMC.

RX 6800 OC Gaming cards will be PCIe 4.0 interface compatible. The number of hardware-accelerated RT cores is set up in a 1:1 creation towards the CU count. The cards released all fall into a high-end to the enthusiast-class category, and are priced as such. The flagship Radeon Radeon RX 6900 XT is to cost 999 USD, the RX 6800 XT costs 649 USD, and the Radeon RX 6800 will cost 579 USD with performance levels matching the completion RTX 3070 running up-to the RTX 3090. It does that by many architectural improvements, but sure, increasing transistor real-estate comes into play as the shader processor count has nearly doubled up over last generational products. Three SKUs with a very similar design, all based on the same chip I stated, and that statement stands. This 16GB GDDR6 graphics card will get the full 80 CUs enabled. Multiply that with 64 shader units, and you’ll count 5120 shading/stream processors.

This card gets 16 GB of GDDR6 memory based on a 256-bit memory bus. So that means 512 GB/s of memory bandwidth and, in fact, would be equal to the bandwidth of the RTX 3070. The TDP listed is 300 watts. This fully enabled Big Navi based chip has a whopping 26.8 billion transistors. The clocks are the same as the 6800 XT at a 2250 GHz boost and 2015 MHz game clock. According to AMD (below), this card will be able to battle with the GeForce RTX 3090. The card will become available on December 8th for 999 USD. The 6800 XT will get 72 CUs multiplied by 64 shader units is 4608 shading processors.

This card gets 16 GB of GDDR6 memory based on a 256-bit memory bus, not to confuse with the new GDDR6X memory NVIDIA is using for RTX 3080 and 3090. So that means 512 GB/s of memory bandwidth and, in fact, would be equal to the bandwidth of the GeForce RTX 3070. The TDP listed is at 300 watts for this product. The 2250 GHz boost clock is spectacular. However, the more average game clock is listed at 2015 MHz. New is a 128 MB infinity cache, which we need to explain in our final review, of course. The card is to battle the GeForce RTX 3080 in performance. This graphics card will cost you a sweet sum of 649,- USD with an availability date of November 18th.

RX 6800 OC Gaming derivative thus is the Radeon RX 6800; this actually the same card as the 6800 XT, but let’s call this somewhat neutered and presumably the favorite card of voice for many BIOS potential tweakers. In its reference design, it is more restrained with 60 CUs and thus 3840 Shading processors. It’s 1815 MHz game clock and 2105 MHz Boost clock frequency is a notch lower as well.

All three cards released by AMD and their board partners will receive GDDR6 memory, 16 GB of them. Again that’s for all three cards. So that means a 256-bit wide memory bus. However, AMD has got a few tricks up their sleeves architecture wise, as they added a big phat cache into the GPU. We’ll talk more about that later though. power consumption wise we’re talking anywhere from 250 running up-to 300 Watts, these are values that sit a bit better than team green where an RTX 3090 can reach 350 Watts even. All cards are DirectX Ultimate compatible, and that naming is just a placeholder for a few extra feature levels such as DirectX Raytracing (DXR), Variable Rate Shading (VRS), Mesh Shaders, and Sampler Feedback.

SAPPHIRE has its Radeon RX 6800 series graphics cards ready as well and is to offer five new cards on the way, the RX 6800 NITRO+ SE, RX 6800 NITRO+ (non-SE), RX 6800 PULSE as well as XT versions of the same cards. The cards all use triple-fan coolers and have a 2.7-slot design based on dual 8-pin PCIe power connectors on all cards as well. The more premium product is the SAPPHIRE Radeon RX 6800 NITRO+ “Special Edition” with the sole difference that it has been fitted with RGB lighting through the fans. The ‘standard’ Radeon RX 6800 NITRO+ does not get that RGB lighting from the front fans but does keep the backside RGB lit theme though. Clock frequencies are 1825 MHz for the base-clock, 1980 MHZ for the game clock, and a boost frequency that locks in at 2190 MHz. The 16GB GDDR6 memory clocks in at 2000 MHz (16 Gbps effective).
