RX 7900 GRE vs RTX 4080 Super: Specs, Performance and Value

The RTX 4080 Super is the faster card by a wide margin, roughly 25-35% ahead at 1440p and 35-50% at 4K according to published benchmark data. It is the right buy for 4K gaming, heavy ray tracing, and DLSS Frame Generation. The RX 7900 GRE is the value pick for 1440p raster gaming. It costs far less, has the same 16 GB of VRAM, and draws less power, but it trails badly in ray tracing and does not reach the 4080 Super’s 4K capability. The deciding question is budget and resolution, not which card is “better”.

Different Price Classes, Same Shortlists

AMD’s RX 7900 GRE first appeared in China in July 2023 and went global at a $549 MSRP. It is a cut-down Navi 31 RDNA 3 chip with 5,120 stream processors, 16 GB of GDDR6, and 64 MB of Infinity Cache. Nvidia’s RTX 4080 Super launched in January 2024 at $999 with 10,240 CUDA cores, 16 GB of fast GDDR6X, and a 64 MB L2 cache. Both now count as previous-generation cards next to the RX 9070 series and RTX 50 series. Buyers comparing used high-end cards, or deciding whether paying much more for the Nvidia card is worth it, still compare these two.

Specification Breakdown

Raster Performance

Sources agree the RTX 4080 Super is clearly faster, and the gap grows with resolution. Aggregate comparison databases report the 4080 Super about 25% ahead on average across large game lists. Resolution-specific estimates put its lead at roughly 35-40% at 1440p and up to about 50% at 4K. Game-by-game data, such as Notebookcheck’s per-title percentage charts, shows the 4080 Super far ahead in many titles. One site testing a CPU-limited reference suite reported only a single-digit gap at 1440p, which shows how much a CPU bottleneck can compress high-end results.

In practical terms, at 1440p ultra both cards deliver high frame rates in most current games. The GRE commonly runs around 80-130 fps and the 4080 Super around 110-170 fps, depending on the title. At 4K the GRE often sits around 50-80 fps in demanding games, while the 4080 Super stays closer to 70-110 fps. These ranges vary with settings, CPU, and game patch. The 4080 Super is a true 4K card. The GRE is a strong 1440p card that can handle 4K with upscaling.

Ray Tracing and Path Tracing

Ray tracing is where the gap is largest. Ada Lovelace’s RT cores are a generation ahead of RDNA 3’s ray accelerators. With heavy ray tracing, the 4080 Super commonly leads by much more than its raster margin, often by well over 50% in RT-heavy titles. Path-traced modes in games like Cyberpunk 2077 and Alan Wake 2 are realistic on the 4080 Super with DLSS and frame generation, but not on the GRE. If ray tracing is a reason you are buying a high-end card, the Nvidia option is the clear choice.

Upscaling and Frame Generation

• RTX 4080 Super: DLSS 4 super resolution with the transformer model, DLSS Frame Generation (one generated frame per rendered frame), Ray Reconstruction, and Reflex. Multi Frame Generation remains exclusive to RTX 50 cards.
• RX 7900 GRE: FSR 3.1 upscaling, FSR 3 frame generation in supported games, and AMD Fluid Motion Frames at the driver level. AMD’s AI-based FSR 4 is officially limited to the RX 9000 series.

DLSS still has the image-quality edge over FSR 3.1, especially in Performance mode at 4K. That widens the practical gap between these cards in games where both upscale.

VRAM and Memory

Both have 16 GB on a 256-bit bus, which is enough for 4K ultra textures in nearly every current game. The 4080 Super’s GDDR6X delivers 736.3 GB/s against the GRE’s 576 GB/s, and its 64 MB L2 is comparable to the GRE’s 64 MB Infinity Cache. Memory capacity is not a reason to choose one over the other. The GRE’s lower bandwidth helps explain why it scales less well at 4K.

Power, PSU, and Physical Fit

The GRE is rated at 260 W with two 8-pin connectors. The 4080 Super is rated at 320 W with a single 16-pin 12VHPWR connector. Most cards include an adapter, but a native ATX 3.0/3.1 power supply cable is cleaner and avoids bending stress at the plug. PSU sizing using GPU TDP + CPU + about 150 W of headroom:

• RX 7900 GRE + 125 W CPU: 260 + 125 + 150 = 535 W, so a quality 650-700 W unit.
• RTX 4080 Super + 125 W CPU: 320 + 125 + 150 = 595 W, so a quality 750 W unit, ideally with a native 16-pin cable.

Size matters more than power here. The reference 4080 Super design is 310 mm long and three slots thick, and many partner versions are larger. Check your case’s GPU clearance and that the 16-pin cable can exit without a tight bend near a side panel. The GRE reference card is 276 mm and two slots wide, though many partner GRE cards are also 2.5-3 slots. On outputs, the GRE offers DisplayPort 2.1 and a USB-C port. The 4080 Super is limited to DP 1.4a, which still drives high-refresh 4K with Display Stream Compression.

Cost per Frame

At launch MSRPs ($549 vs $999), the 4080 Super cost about 82% more. With roughly 30% more raster performance at 1440p, each 4080 Super frame cost about 40% more than a GRE frame at launch prices ($999 / 1.3 is about $768 per GRE-equivalent unit vs $549). At 4K, with the 4080 Super about 45% faster, it still cost around 25% more per frame. Neither figure accounts for the 4080 Super’s ray-tracing lead or DLSS Frame Generation. On the used market, GRE cards usually sell for around $400-$480 and 4080 Super cards for around $750-$900, so the ratio stays roughly the same.

If you are shopping new in 2026, the RX 9070 and RTX 5070 Ti also sit in this range, and they are worth pricing before committing to either previous-generation card.

Choosing Between Them

Frequently Asked Questions

How much faster is the RTX 4080 Super than the RX 7900 GRE?

In rasterized games, benchmark data puts it roughly 25-35% ahead at 1440p and around 35-50% ahead at 4K. With heavy ray tracing, the gap is considerably larger. CPU-limited tests at lower resolutions show smaller differences.

Is the RX 7900 GRE good for 4K?

It can run many games at 4K, especially with FSR upscaling and settings slightly below maximum. It is more comfortable at 1440p, where its 16 GB of VRAM and strong raster performance give high frame rates. For native 4K at ultra settings, the RTX 4080 Super is far more capable.

Do both cards have enough VRAM?

Yes. Both have 16 GB on a 256-bit bus, which covers 4K ultra textures in nearly all current games. The 4080 Super’s faster GDDR6X gives it more bandwidth, but capacity is identical.

What PSU do I need for the RTX 4080 Super?

A quality 750 W power supply is a sensible target with a typical high-end CPU. A native 16-pin cable from an ATX 3.0 or 3.1 unit is preferable to the adapter. Make sure the cable is fully seated and not bent sharply near the connector.

Will the RTX 4080 Super fit in my case?

The reference design is 310 mm long and three slots thick, and many partner cards are longer. Measure your case’s GPU clearance and leave space for the power cable to bend gently. The RX 7900 GRE reference card is shorter at 276 mm.
