RX 7900 GRE vs RTX 5070: Specs, Performance and Value

For most new 1440p builds the RTX 5070 is the better buy: it lands slightly ahead of the RX 7900 GRE in raster games, pulls clearly ahead with ray tracing, and gets DLSS 4 with Multi Frame Generation. The RX 7900 GRE still makes sense if you find it noticeably cheaper (often on the used market) or if you play heavily modded or texture-hungry games where its 16 GB of VRAM matters more than the 5070’s 12 GB.

Both cards launched at the same $549 MSRP, roughly 19 months apart, and they target the same buyer: someone gaming at 1440p who wants high settings without paying flagship prices. The interesting part is that they get there in very different ways. AMD’s card relies on a wide 256-bit memory bus and a big Infinity Cache, while NVIDIA’s leans on newer GDDR7 memory, a large 48 MB L2 cache and a much stronger feature stack.

Specifications Side by Side

Raw shader counts are not directly comparable across AMD and NVIDIA designs, so the table is more useful for memory, power and physical fit than for predicting frame rates. The key takeaways: the GRE has more VRAM, the 5070 has more bandwidth despite the narrower bus thanks to GDDR7, and the two draw almost identical rated power.

Raster Performance: Closer Than the Marketing Suggests

In traditional rasterized games the gap is small. According to TechPowerUp’s RTX 5070 review data, the 5070 lands roughly 10% ahead of the RX 7900 GRE at 1440p, and the reviewer described it as sitting between the RX 7900 GRE and RX 7900 XT. Hardware Unboxed’s later testing put the RX 9070 GRE level with the RX 7900 GRE and about 5% behind the RTX 5070 across 15 games at 1440p, which implies a similar single-digit lead for NVIDIA. Aggregate benchmark sites land anywhere from a near tie to about 7% in favor of the 5070.

Taken together, a fair summary is that the RTX 5070 is about 0-10% faster in raster at 1080p and 1440p, with individual games swinging either way. Titles that favor AMD’s architecture (some Call of Duty entries and certain console ports) can put the GRE in front. At 4K the 5070 generally keeps a small lead, though that is also where its 12 GB buffer can start to pinch in the heaviest games.

For approximate frame rates, both cards typically deliver somewhere around 80-120 fps in demanding modern games at 1440p high settings and well above 144 fps in esports titles. Those ranges vary considerably with game, settings, CPU and driver or game patch, so treat them as a guide rather than a promise.

Ray Tracing and Path Tracing

This is where the two cards separate. TechPowerUp noted that the RTX 5070’s ray tracing performance is strong enough to beat even AMD’s RX 7900 XTX in its RT test suite, and the RX 7900 GRE sits well below the XTX. In games with heavy RT effects such as Cyberpunk 2077, Alan Wake 2 or Black Myth: Wukong, the 5070’s lead commonly grows into the 25-50% range, and in path-traced modes the GRE becomes impractical without aggressive upscaling.

If ray tracing is something you actually turn on, the decision is easy. If you mostly play competitive shooters or older titles with RT off, the difference shrinks to the small raster gap described above.

Upscaling and Frame Generation

• RTX 5070: DLSS 4 with the transformer-based Super Resolution model, DLSS Frame Generation and Multi Frame Generation (up to several generated frames per rendered frame). DLSS is supported in a very large share of new releases.
• RX 7900 GRE: FSR 3.1 upscaling and frame generation, plus driver-level AFMF. AMD’s machine-learning FSR 4 is officially built for RDNA 4 cards, so RDNA 3 owners do not get it as an officially supported feature. FSR 3.1 works well at 4K Quality mode but shows more shimmering at 1440p in lower presets than DLSS 4.

In practice, upscaled image quality at 1440p is a real advantage for the 5070. Multi Frame Generation can lift displayed frame rates dramatically, but it works best when the base frame rate is already around 60 fps; it smooths motion rather than reducing input latency.

VRAM: 16 GB vs 12 GB

The GRE’s extra memory is its strongest long-term argument. A rough guide for current games:

• 1080p: 8-10 GB is usually enough; both cards have plenty.
• 1440p: 10-12 GB covers most games at high or ultra textures; the 5070 is fine but has less margin when ray tracing and frame generation are stacked, since both consume extra VRAM.
• 4K: 12-16 GB is increasingly needed for maximum textures; the GRE has the headroom, while the 5070 may need texture quality dropped one notch in a handful of games.

For players who keep a card four or five years, or who run large texture mods, the 16 GB buffer is a genuine hedge. For a 1440p player who upgrades every two or three generations, 12 GB is workable today.

Power, PSU and Case Fit

A simple sizing rule is GPU TDP plus CPU power plus about 150 W of headroom. With a typical gaming CPU drawing around 120 W under load:

• RX 7900 GRE: 260 + 120 + 150 = 530 W, so a quality 600-650 W unit is a comfortable choice.
• RTX 5070: 250 + 120 + 150 = 520 W, so the same 600-650 W class works.

The connector situation differs. The GRE uses two standard 8-pin PCIe plugs, which any reasonable PSU provides. The 5070 uses a single 16-pin (12V-2×6) connector; reference and most partner cards include an adapter for 8-pin cables, but a native ATX 3.x cable is the tidier option. Make sure the 16-pin plug is fully seated.

For case fit, the reference 5070 is 245 mm long versus 276 mm for the GRE, which matters in compact mid-towers and small-form-factor builds. Partner models of both cards vary widely, and many triple-fan versions exceed 300 mm, so check the specific model against your case’s GPU clearance.

Value at Launch Prices

Because both launched at $549, cost per performance at MSRP simply follows relative speed. If the GRE is indexed at 100 and the 5070 at roughly 105-110 in raster, the 5070 delivers about 5-10% more raster performance per dollar, and considerably more once ray tracing is factored in. The GRE only wins on value when it is meaningfully cheaper: at roughly 10-15% below the 5070’s going price, raster performance per dollar evens out, and the 16 GB of VRAM becomes a bonus.

The RX 7900 GRE is a previous-generation card, so new stock has thinned and much of the supply is now used. Used GRE cards commonly sell somewhere in the $350-$450 range depending on model and condition, which is where it becomes a strong alternative.

Which One to Pick

Frequently Asked Questions

Is the RTX 5070 faster than the RX 7900 GRE?

Yes, in most cases. Published reviews put the RTX 5070 roughly 0-10% ahead in raster games at 1440p, and well ahead with ray tracing enabled. A few AMD-friendly titles still favor the GRE.

Is 12 GB of VRAM on the RTX 5070 enough?

For 1080p and 1440p it is enough in nearly all current games. At 4K with maximum textures, ray tracing and frame generation combined, some titles can exceed 12 GB, and lowering texture quality one step fixes it. The RX 7900 GRE’s 16 GB gives more margin for long ownership.

Can the RX 7900 GRE use FSR 4?

FSR 4 is officially supported on AMD’s RDNA 4 cards, while the RX 7900 GRE is RDNA 3. The GRE officially uses FSR 3.1 upscaling and frame generation, plus AMD Fluid Motion Frames at the driver level.

What power supply do I need for either card?

A good-quality 600-650 W PSU is enough for either card with a mainstream gaming CPU. The GRE needs two 8-pin cables, while the RTX 5070 uses one 16-pin connector, usually with an adapter in the box.

Should I buy a used RX 7900 GRE instead of a new RTX 5070?

If the used GRE costs noticeably less and you mainly play without ray tracing, it is a reasonable value pick. You give up DLSS 4, stronger ray tracing and a fresh warranty, so the discount should be meaningful, roughly 15% or more.
