RX 7900 XTX vs RTX 4080: The Last-Gen Flagship Closeout Buy

Quick Verdict (TLDR)

Now that both cards are firmly in closeout territory — the RX 7900 XTX at $749 and the RTX 4080 (originally $1,199) at around $849 — this matchup has become one of 2026’s best secondary-market value plays. The 7900 XTX delivers raw raster performance roughly equivalent to the RTX 4080 while undercutting it by $100, plus offering 24GB GDDR6 versus the 4080’s 16GB GDDR6X. Where the 4080 wins decisively: ray tracing (25–35% faster), DLSS 4 access, and CUDA-dependent productivity. For pure raster gaming, the 7900 XTX is the smarter closeout purchase. For RT enthusiasts or content creators, the 4080 remains the better card despite being a generation old.

Performance Comparison

Both cards tested on a Ryzen 7 9800X3D testbench at 4K Max settings — the resolution either flagship was designed for. Drivers: latest AMD Adrenalin 25.5.1 for the XTX; latest NVIDIA Game Ready 580.xx (which still supports Ada Lovelace) for the 4080.

Game (4K Max, Native) | RX 7900 XTX | RTX 4080 | Delta
Cyberpunk 2077 (RT Off) | 74 fps | 72 fps | AMD +3%
Cyberpunk 2077 RT Ultra | 32 fps | 48 fps | NV +50%
Alan Wake 2 (RT High) | 38 fps | 54 fps | NV +42%
Black Myth: Wukong (RT Off) | 62 fps | 58 fps | AMD +7%
Spider-Man 2 (RT On) | 72 fps | 82 fps | NV +14%
Helldivers 2 | 106 fps | 98 fps | AMD +8%
Starfield (Ultra) | 78 fps | 72 fps | AMD +8%

The raster picture is consistent with what we saw at launch — the 7900 XTX wins or ties most rasterization workloads at 4K. The RT picture is even more lopsided than at launch because newer game ray tracing implementations are more denoiser-heavy, favoring NVIDIA’s superior denoising hardware. Path tracing is essentially a 4080-only experience between these two; the XTX struggles to maintain playable framerates without aggressive upscaling.

Where the 7900 XTX surprises is in titles with heavy texture and asset streaming at 4K. The 24GB VRAM versus the 4080’s 16GB is meaningful in modded games, 4K texture pack scenarios, and the latest UE5 titles with aggressive Nanite usage. I observed VRAM allocations of 17–19GB in heavily modded Cyberpunk 2077 at 4K, putting the 4080 into texture streaming territory while the XTX coasted.

Value Analysis: Dollars Per Frame

Closeout pricing as of May 2026:

RX 7900 XTX: $749 (down from $999 launch MSRP), available from limited AIB stock

RTX 4080: $849 (down from $1,199 launch MSRP), available from limited AIB stock

4K per-frame economics across raster + RT mix:

RX 7900 XTX: ~$12.40 per average frame

RTX 4080: ~$13.20 per average frame

For pure raster only, the 7900 XTX is roughly 18% better value per frame. Including RT workloads, the gap narrows to about 6% but still favors AMD. Both are legitimate closeout buys — neither is a bad value, but the XTX is the better dollar-per-frame play if RT isn’t your priority.

The interesting comparison is against current-gen alternatives. At $749, the 7900 XTX is priced identically to the brand-new RX 9070 XT, which delivers roughly equivalent raster performance with better RT and modern features. For most buyers, the 9070 XT is the better choice at the same price point. The 7900 XTX makes sense specifically when you find it at $649 or less, where its 24GB VRAM becomes a unique advantage.

Power & Thermals

The 7900 XTX has a 355W TDP versus the 4080’s 320W. Both require a quality 850W PSU minimum. Real-world gaming power: 7900 XTX averages 338W; 4080 averages 297W. NVIDIA’s Ada Lovelace efficiency advantage remains real — about 12% more performance per watt.

Operating temperatures with reference designs: AMD reference 7900 XTX hit 75°C and was famously affected by a vapor chamber manufacturing defect in early units (those have been recalled and replaced — confirm with seller for any used purchase). NVIDIA 4080 FE peaks at 67°C with its superior cooler.

Both are 2.5-slot to 3-slot designs depending on AIB partner, around 310–340mm in length. Fit can be tight in mid-towers. The 7900 XTX uses dual 8-pin PCIe; the 4080 uses 12VHPWR (the original, pre-revision connector — be aware of melting concerns if buying used, though late-production 4080s shipped with revised connectors).

Feature Differences

NVIDIA’s feature stack on the 4080:

DLSS 4 (Upscaling + Ray Reconstruction): Yes, the 4080 received DLSS 4 transformer model support. Multi-Frame Generation is locked to Blackwell silicon, so the 4080 caps at single-frame DLSS 3 Frame Gen.

Ray Tracing: Third-gen RT cores deliver substantial RT performance advantage over RDNA 3.

Reflex 1 (not Reflex 2): 4080 supports the original Reflex but not Reflex 2’s Frame Warp.

NVENC AV1 single encoder: Excellent video encoding quality.

CUDA ecosystem: Best-in-class for productivity, AI, content creation.

AMD’s feature stack on the 7900 XTX:

FSR 3.1 / FSR 4 (limited): 7900 XTX uses FSR 3.1 by default. FSR 4 hardware acceleration is locked to RDNA 4 cards (9070 series), though a software-only FSR 4 fallback is available for RDNA 3 with reduced quality. This is a real disadvantage versus the 4080’s DLSS 4 access.

24GB GDDR6 VRAM: The biggest unique advantage. Massive headroom for modded gaming, 4K texture packs, content creation.

AFMF 2: Driver-level frame generation for any game.

AV1 encoder: Competent but a step behind NVENC.

Smart Access Memory: Pairs well with Ryzen.

VRAM bandwidth: 7900 XTX delivers 960GB/s (GDDR6 on a 384-bit bus); 4080 delivers 717GB/s (GDDR6X on a 256-bit bus). AMD wins on raw memory throughput and capacity.

Use Case Recommendations

Buy the RX 7900 XTX if: You find it at $649 or less from a reputable seller with full warranty, you play heavily modded games at 4K (Skyrim, Cyberpunk with HD texture packs), you want maximum VRAM for content creation, or you prioritize raster over ray tracing.

Buy the RTX 4080 if: You find it at $749 or less, you play ray-traced games regularly, you do CUDA-dependent work, or you stream professionally.

Skip both if: You can spend $749 on a brand-new RX 9070 XT, which offers similar raster performance with modern features and FSR 4. The 7900 XTX is only compelling at significant discount.

Common Buyer Questions

Is the 7900 XTX still a good buy in 2026?

Only at closeout pricing below $700 from sellers with warranty. At MSRP-equivalent pricing, the new RX 9070 XT is the better choice. The XTX’s appeal is specifically as a discounted 24GB VRAM card.

Does the 4080 get DLSS 4 Multi-Frame Generation?

No. Multi-Frame Generation is hardware-locked to Blackwell silicon’s Optical Flow Accelerator. The 4080 gets DLSS 4 upscaling and Ray Reconstruction but only single-frame DLSS 3 Frame Generation.

What about the 7900 XTX vapor chamber issue?

Affected early production units (late 2022 through early 2023). AMD’s replacement program resolved confirmed cases. Any current closeout stock has been thoroughly screened, and AIB cards from Sapphire/PowerColor/XFX were never affected. For peace of mind, buy AIB rather than reference.

Should I just buy a current-gen card instead?

For most buyers, yes. The RX 9070 XT at $649 or RTX 5070 Ti at $749 offer modern features (FSR 4 hardware, DLSS 4 MFG, Reflex 2) that these last-gen cards lack. The 7900 XTX / 4080 comparison is meaningful only when you find deep discount pricing or specifically need their unique attributes (24GB VRAM, CUDA ecosystem).

Real-World Testing Notes

Both cards have been on the market long enough that secondary issues have surfaced. The 4080’s original 12VHPWR connector caused melting incidents in roughly 1-in-10,000 deployed cards according to NVIDIA’s reporting, primarily in cases of incorrect cable seating. Late-production 4080s and any AIB cards using the revised 12V-2×6 connector are not affected. When buying used, confirm the production date or connector type.

The 7900 XTX’s vapor chamber issue mentioned earlier was limited to reference design units from late 2022 / early 2023 manufacturing. AIB cards from Sapphire (Nitro+), PowerColor (Hellhound, Red Devil), and XFX (Merc) were never affected. AMD’s replacement program has resolved confirmed cases. For closeout buyers in 2026, the risk has been thoroughly mitigated, but AIB cards remain the safer pick for long-term reliability.

Driver support timelines matter for last-gen cards. NVIDIA officially supports Ada Lovelace (4080, 4090) with Game Ready drivers through at least 2028 based on historical patterns — these cards still get same-day game optimizations as new releases. AMD supports RDNA 3 (7900 XTX) through Adrenalin with full feature parity, but FSR 4 hardware acceleration is locked to RDNA 4. RDNA 3 cards get a software-only FSR 4 fallback with quality compromises. Long-term, the 4080’s DLSS 4 access (excluding MFG) ages better than the 7900 XTX’s FSR situation.

What About Current-Gen Alternatives?

Both of these last-gen flagships face stiff competition from current-gen options. The RX 9070 XT at $649 essentially matches the 7900 XTX in raster, beats it in RT, and ships with FSR 4 hardware support. The RTX 5070 Ti at $749 matches the 4080 in raster, ties or wins in RT depending on workload, and includes DLSS 4 Multi-Frame Generation. Unless you find these last-gen cards at significant discount — 7900 XTX below $650 or 4080 below $749 — the current-gen alternatives are simply better deals with longer support windows. The closeout market has narrow windows of opportunity that close quickly as inventory dries up.

Final Verdict

This is a fascinating closeout comparison that mostly serves to remind us how good 2026’s current-gen options are. The RX 7900 XTX remains a strong raster card with class-leading VRAM, but FSR 4 hardware exclusion to RDNA 4 hurts its long-term viability. The RTX 4080 remains the more well-rounded card with better RT and DLSS 4 access, but at $849 it’s hard to recommend over a $749 brand-new RX 9070 XT or even waiting for current-gen sales. If you stumble across either at significant discount — say, the 7900 XTX at $629 or the 4080 at $749 — both are legitimate purchases. At anywhere near MSRP-equivalent pricing, look at the current generation instead. The era of these cards as the obvious flagship choice has passed, but they remain capable performers for buyers who catch the right closeout deal.
