AMD is refreshing its RX 6000 graphics cards, which were launched a year and a half ago in November 2020. Between the RX 6650 XT and RX 6950 XT, we have the new RX 6750 XT, a replacement for the RX 6700 XT that was launched in March 2021. This upper-mid GPU range is positioned against Nvidia’s RTX 3070, so we threw them both into the ring to see how they stack up.
The RX 6750 XT hasn’t launched yet, so we’re relying on AMD’s benchmarks for now. Although AMD is not lying, it definitely wants to show this GPU in a positive light compared to the best graphics cards.
Prices and availability

The RX 6750 XT is not just a price cut for the RX 6700 XT. In fact, AMD is launching the RX 6750 XT at $549, a $70 increase in MSRP over the RX 6700 XT, which launched at $479. The closest competitors on the Nvidia side are the RTX 3070 and RTX 3070 Ti, which launched with prices of $499 and $549, respectively.
The shortage of GPUs over the past 2 years has shown that MSRP doesn’t always mean much, but over the past month the shortage has almost narrowed, at least for AMD GPUs. In the past month, the RX 6700 XT has been seen multiple times for less than $549, and even as low as $484 with rebates. The RTX 3070 and RTX 3070 Ti are usually in the $600-$800 range.

If you want to compare the RX 6750 XT with the RTX 30709, we recommend that you focus only on memory size and TDP. It’s hard to compare the specs of GPUs from different families, especially when the GPUs aren’t even made by the same company.
| RX 6700 XT | RX 6750 XT | RTX 3070 | |
| GPU | Navi 22 | Navi 22 | GA104-300 |
| Interface | PCI Express 4.0 | PCI Express 4.0 | PCI Express 4.0 |
| CUDA cores/stream processors | 2,560 | 2,560 | 5,888 |
| Ray Tracing Accelerators | 40 air accelerators | 40 air accelerators | 42 RT cores |
| Tensor kernels | ON | ON | 184 |
| Game clock | 2.424 MHz | 2.495 MHz | 1.730 MHz |
| Memory | 12 GB GDDR6 | 12 GB GDDR6 | 8 GB GDDR6 |
| Memory bus | 192-bit | 192-bit | 256-bit |
| Band width | 384 GBps | 432 GBps | 448 GBps |
| TDP | 230 watts | 250 watts | 220 watts |
AMD has improved the RX 6700 XT by giving the RX 6750 XT a 2.9% higher clock speed and faster 18Gbps GDDR6 memory, which means 12.5% more memory bandwidth. The RX 6750 XT is otherwise identical to the RX 6700 XT.
Considering the slight improvement in clock speed and the much more significant increase in memory bandwidth, AMD must think that the original RX 6700 XT didn’t have enough bandwidth. In the benchmarks below, we’ll see if we should expect that extra bandwidth to be useful.
Performance

AMD tested the RX 6750 XT, RX 6700 XT, and RTX 3070 in 15 games at 1440p, and the 6750 XT benchmarks below come from AMD’s test system using a Ryzen 7 5800X3D (the fastest gaming CPU) and 32GB of DDR4 memory on 3600MHz.
We’ll compare their results to our RX 6700 XT review to put AMD’s data into context, as AMD is clearly not the most unbiased source of performance data. According to AMD’s own data, on average the RX 6750 XT is about 7% faster than the RX 6700 XT, and its advantage ranges from 6-9% depending on the game.
| AMD benchmarks: RX 6750 XT vs RTX 3070 | Our benchmarks: RX 6700 XT vs. RTX 3070 | |
| Assassin’s Creed Valhalla | +21% | 0% |
| Battlefield V | +9% | -11% |
Compared to the RTX 3070, the RX 6750 XT packs a punch in most games. AMD’s numbers show that it leads the way Assassin’s Creed Valhalla and Borderlands 3 although lagging behind in Forza Horizon 5 and Metro Exodus. Note that AMD has run its tests with Smart Access memory, which should improve performance on an all-AMD system.
AMD didn’t provide exact numbers, but the RX 6750 XT seems to perform roughly on par with the RTX 3070, which is surprising. Our testing of the RX 6700 XT showed an edge over Nvidia’s rival card, so we’ll have to wait for third-party benchmarks to get a full picture of performance.
Scaling up and ray tracing

Today, both AMD and Nvidia rely on software upscalers to get better image quality and more performance. An upscaler is basically an algorithm that can make a low resolution image look high resolution. Nvidia’s Deep Learning Super Sampling (or DLSS) is more mature than AMD’s equivalent, FidelityFX Super Resolution (or FSR), but they’re not quite the same.
DLSS requires Tensor cores, which means that no AMD GPU can use it, only Nvidia 20 or 30 series GPUs. Meanwhile, the minimum requirement for FSR is an RX 590 (which launched in 2017) or a GTX 1070, which makes AMD’s support for Nvidia GPUs actually better than Nvidia’s support for its own GPUs. DLSS is currently considered the superior upscaler, but Nvidia’s advantage may soon end as FSR 2.0 is due to be released this summer.
The other big thing the two graphics companies have focused on is ray tracing. Nvidia’s ray tracing performance is significantly better than AMD’s. However, on both Nvidia and AMD hardware, ray tracing is very intensive and reduces frames per second significantly.
Where does the RX 6750 XT fit in?
Due to the increased MSRP, the RX 6750 XT is in an awkward spot. It can’t compete with the RX 6700 XT when it comes to value, which makes this refresh puzzling, especially since the RX 6700 XT seems like a good deal. Users would undoubtedly be unhappy if AMD discontinued the RX 6700 XT, given its better value for money.
Other GPUs with similar MSRPs such as the RX 6800, RTX 3070, and RTX 3070 Ti still sell at inflated prices, so the 6750 XT is a viable, if slower, alternative as long as it’s in good supply.
