| Ray Accelerators | 40 | 60 |
| Base / Boost Clock | ~2150 MHz / ~2600 MHz | ~2030 MHz / ~2490 MHz |
| VRAM | 12GB GDDR6 | 16GB GDDR6 |
| Memory Bus | 192-bit | 256-bit |
| Memory Bandwidth | ~432 GB/s | ~624 GB/s |
| TDP | 250W | 263W |
Note:
- Together with additional VRAM and a bigger memory bus, the RX 7800 XT boasts a noticeably higher number of stream processors and ray accelerators.
- Its chiplet architecture enhances efficiency and performance.
- Despite its strength, the RX 6750 XT is archaic compared to RDNA 3.
Gaming Performance Comparison
In gaming, performance is everything. Both GPUs target high-refresh 1440p gaming, while the RX 7800 XT’s improved hardware allows smoother 4K gameplay in some games.
Performance Benchmarks (Average FPS at 1440p, Ultra Settings)
| Game | Radeon RX 6750 XT | Radeon RX 7800 XT |
|---|---|---|
| Cyberpunk 2077 (Ray Tracing Off) | 54 FPS | 75 FPS |
| Assassin’s Creed Valhalla | 82 FPS | 106 FPS |
| Call of Duty: Modern Warfare II | 110 FPS | 142 FPS |
| Red Dead Redemption 2 | 72 FPS | 98 FPS |
| Forza Horizon 5 | 106 FPS | 138 FPS |
Observations:
- Popular AAA games run 25-35% faster on the RX 7800 XT.
- Smoother gaming, especially on 120Hz or 144Hz panels, results from this upgrade.
- Minimum frame rates are greater on the RX 7800 XT, minimising stutter and enhancing consistency.
Performance Ray Tracing
- Second-generation ray accelerators improve ray-traced effects in the RX 7800 XT.
- First-generation RT cores in the RX 6750 XT suffer with heavy ray tracing, resulting in low frame rates unless settings are severely decreased.
- The RX 7800 XT is best for ray tracing at watchable frame rates.

Feature Set and Technology
AV1 Encoding/Decoding
The RX 7800 XT’s hardware support for AV1 encoding and decoding is one of its best qualities. A newer video codec called AV1 delivers higher compression efficiency than more established ones like HEVC and H.264. Because of this, content producers and streamers that desire high-quality video streaming at a reduced bandwidth consumption find the 7800 XT to be quite appealing.
The RX 6750 XT’s usefulness for contemporary video processes is limited by its inability to encode video in AV1.
Display Outputs
- RX 6750 XT: Typically comes with DisplayPort 1.4 and HDMI 2.1 ports.
- The RX 7800 XT can now support 4K gaming at very high refresh rates and even 8K TVs with its enhanced bandwidth output from the upgrade to DisplayPort 2.1 and HDMI 2.1.
Because of this, those who have expensive displays or intend to upgrade will find the RX 7800 XT to be a more future-proof option.
FidelityFX Super Resolution (FSR)
The FidelityFX Super Resolution (FSR) spatial upscaling technology from AMD, which increases frame rates by rendering at a lesser resolution and upscaling to native resolution, is supported by both graphics cards.
- The RX 7800 XT supports FSR 3.0, which doubles frame rates in games that are compatible.
- Although the RX 6750 XT supports FSR 2.x, it does not support the most recent frame generation technology, hence there is less performance boost.
Software & Driver Improvements
Better power management, updated driver optimisations, and enhanced compatibility with AMD’s Smart Access Memory (SAM) technology which can marginally boost performance when paired with compatible AMD Ryzen CPUs are all advantages of RDNA 3 GPUs.
Power Consumption & Efficiency
Despite having a larger TDP (263W vs. 250W), the RX 7800 XT performs better per watt with its sophisticated 5nm technology and chiplet design. This translates to a little bit more power for better game performance.
Normal temperatures for operation:
- RX 6750 XT: 72–75°C Under load,
- RX 7800 XT: 68–72°C under load (often runs cooler due to architectural improvements)
In general, the 7800 XT operates more effectively and has superior thermals, particularly in cases with adequate ventilation.
Who Should Buy Which?
Radeon RX 7800 XT:
- You want the best 1440p performance and entry-level 4K gaming.
- You intend to include ray tracing into contemporary games.
- Future-proof features like DisplayPort 2.1 and AV1 support are important to you.
- You want to create or broadcast multimedia and take use of AV1 hardware encoding.
- You desire cooler operation and maximum efficiency.
Radeon RX 6750 XT:
- You want to play games at 1440p with good performance, but you have a limited budget.
- You mostly play older or less difficult games without ray tracing.
- AV1 encoding and the most recent display output standards are not required.
- This GPU is reasonably priced in the used or reduced market.
RX 6750 XT VS RX 7800 XT Pricing
| Model | MSRP at Launch | Current Market Price (2024) |
|---|---|---|
| RX 6750 XT | $549 | $330–$400 |
| RX 7800 XT | $499 | $480–$520 |
- Due to its age, the RX 6750 XT is discounted, making it appealing to budget-conscious gamers.
- Although newer, the RX 7800 XT launched with a competitive MSRP and delivers greater value for lifetime and future-proofing.
- Many purchasers consider the RX 7800 XT worth the extra money for its performance and features when the price difference narrows in real life.
In conclusion
The RX 7800 XT’s combination of more VRAM, improved power efficiency, and cutting-edge technology makes it the better option for enthusiasts or those creating a gaming PC that is ready for the future, even though the RX 6750 XT is still a good card for popular 1440p gamers.
In the end, your decision should take into account your spending limit, your gaming goals, and how crucial the newest features and performance headroom are to your PC configuration.
