What this page is—and isn’t
This is not a TWW hands-on review. TWW has not physically tested or independently benchmarked this product. This page organizes the manufacturer’s specifications, practical buying considerations and links to published external testing where available.
Any performance or usability conclusions attributed to an outside publication remain that publication’s findings. They are not presented as TWW measurements.

Specifications can vary by region, exact SKU, firmware, and manufacturer updates. Confirm the seller’s exact part number before purchase.
What independent testing reports
Both January 2025 reviews tested Founders Edition samples against the RTX 4090. TechSpot found a 27% average 4K gain and called the card a faster RTX 40-series part with poor value, while Tom’s Hardware found 25% at 4K Ultra, much smaller gains at lower resolutions, and raised thermal and connector concerns at full power, attributing some inconsistent results to immature drivers. Those are the outlets’ findings on their own test systems, not TWW measurements, and they predate later driver updates.

Configuration note: The reviews tested Founders Edition cards. Partner cards differ in cooling, size, noise and power behavior, so confirm the exact model before applying the findings.
Potential strengths
- 32GB of GDDR7 on a 512-bit interface is a very large memory configuration for a consumer graphics card.
- TechSpot measured a 27% average gain over the RTX 4090 at 4K across 17 games, and Tom’s Hardware measured 25% at 4K Ultra across 16 games.
- TechSpot called the Founders Edition cooler an outstanding achievement, and Tom’s Hardware measured about 50dB of noise at a constant 575W load.
Limitations and buying cautions
- Gains shrink at lower resolutions: Tom’s Hardware measured 13% at 1440p Ultra and 3% at 1080p Ultra, and TechSpot noted 1440p results were often CPU-limited.
- TechSpot measured around 30% more power than the RTX 4090 and judged the value poor, calling it essentially a faster RTX 40-series card.
- Tom’s Hardware recorded 94°C and some instability at the 575W power limit in Cyberpunk 2077, called that unacceptable for the class, and questioned whether the 12V-2x6 connector can reliably carry 575W.
Who should consider it?
- 4K high-refresh gaming with a very large budget
- Buyers who skipped the RTX 4090 and want the fastest consumer card (TechSpot’s framing)
- Builders with a high-end CPU and a power supply that meets NVIDIA’s requirements
