RTX 5080 vs RTX 4080 Super: Generational GPU Comparison

Specifications

RTX 5080 uses Blackwell GB203, launched 30 January 2025, with 10,752 CUDA cores, 84 RT cores, 336 Tensor cores, 16GB GDDR7, 256-bit bus, 960 GB/s bandwidth, 360W total graphics power, and 850W PSU, per the Lap 7 research. RTX 4080 Super uses Ada Lovelace AD103, launched 8 January 2024, with 10,240 CUDA cores, 80 RT cores, 320 Tensor cores, 16GB GDDR6X, 256-bit bus, 736.3 GB/s bandwidth, 320W total graphics power, per the 2026-10-31 search (Technical City, NanoReview).

For everyday work, both GPUs are fast. For multitasking, the 5080 offers 5% more cores, against the Super, so the 5080 fits slightly more tasks without an upgrade. For memory, both offer 16GB, so both fit the same model size and texture budgets.

Performance

No single controlled test covers every game, so this article uses published benchmark summaries with their sources named. Technical City aggregate found the 5080 about 4.2% ahead, with scores 85.22 vs 81.77, per the 2026-10-31 search. NanoReview found the 5080 about 11% higher average frame rate at QHD, 165 vs 149 FPS, per the same search. Aivanet found the 5080 about 18% faster on average than the 4080 Super, per the same search. No universal winner is claimed, because the gap varies by title and method.

For students, both GPUs should handle notes, browsing, documents and light coding easily. For creators, the 5080 should help more in rendering, while the Super should help more in value. For developers, both GPUs should handle compilation and local AI, with the 5080 helping more in compute, and the Super helping more in efficiency.

Gaming

For gaming, the 5080 wins clearly, with 10,752 CUDA cores and GDDR7, against the Super's 10,240 cores and GDDR6X. Both offer 16GB memory, so both should play games well, but not AAA gaming at the same level. OreateAI found God of War at 114 FPS vs 99 FPS at 4K, per the 2026-10-31 search. For texture-heavy mods, both should be similar, because both offer 16GB.

For gamers at 1440p, the 5080 is strong, with 10,752 cores. For gamers at 1080p, the 5080 is strong, with 10,752 cores. For gamers who use ray tracing, the 5080 benefits, with 84 RT cores helping in heavy scenes.

AI performance

RTX 5080 offers 1,801 AI TOPS, per the Lap 7 research, and 16GB memory, so it should handle local AI models well. RTX 4080 Super offers 855 AI TOPS, per ASUS India, and 16GB memory, so it should handle local AI models well. No controlled side-by-side AI test between these exact two GPUs was reviewed beyond those TOPS figures, so no AI winner is claimed beyond the memory and TOPS figures, but TOPS counting differs between vendors.

For local LLM research, both GPUs are strong, because both offer 16GB memory, so both fit a similar model size. For photo and video AI features, both GPUs should handle them, with the 5080 helping more in compute, and the Super helping more in efficiency.

Display

Display is not a GPU feature, but the outputs differ. The 5080 offers DisplayPort 2.1b and HDMI 2.1b, while the Super offers DisplayPort 1.4a and HDMI 2.1b, per ASUS India. For colour work, both GPUs are excellent, with 16GB memory helping in large textures. For gaming, both GPUs are excellent, with DLSS 4 on the 5080 and DLSS on the Super. For outdoor work, both GPUs are similar, with varied monitor brightness.

Battery

Battery is not a GPU feature, but power differs. RTX 5080 uses 360W total graphics power, per the Lap 7 research, with 850W PSU recommended. RTX 4080 Super uses 320W total graphics power, per the 2026-10-31 search. No controlled power-draw test beyond those figures was reviewed, so no power winner is claimed beyond the TDP figures. For travel, neither GPU is portable, because both are desktop cards. For desk work, power matters, because the 5080 needs a larger PSU.

Thermals

RTX 5080 uses 360W, so it should be louder under load, while the Super's fans should be quieter. RTX 4080 Super uses 320W, so it should be quieter under load, while the 5080's fans should be louder. No controlled thermal or fan-noise test between these exact two GPUs was reviewed, so no temperature or noise winner is claimed beyond the cooling designs. For sustained rendering, the 5080's larger core count should help more. For silent work, the Super should be quieter.

Price

RTX 5080 launched at $999 US, per the Lap 7 research, with HowManyFPS street price $1,319.99, per the Lap 7 research. RTX 4080 Super launched at $999 US, per the 2026-10-31 search (Technical City). The launch gap was $0 US, per those sources. India prices for these exact cards were not confirmed, so no India price is claimed. US prices exclude sales tax, while India prices include GST, so headline numbers are not directly comparable.

For a like-for-like setup, both launched at the same price, but the 5080 includes GDDR7, against the Super's GDDR6X. For value buyers who already own a Super, staying put is justified; for new high-end buyers, the 5080's GDDR7 is justified.

Verdict

Buy RTX 5080 if you need GDDR7 and DLSS 4, at $999 launch. Keep RTX 4080 Super if you already own it, at $999 launch. For most new high-end buyers, the 5080 wins; for most existing Super owners, upgrading is optional.
