RTX 5080 vs RTX 5070 Ti: Performance and Price Comparison

Specifications

RTX 5080 uses Blackwell GB203, launched 30 January 2025, with 10,752 CUDA cores, 84 RT cores, 336 Tensor cores, 16GB GDDR7 at 30 Gbps, 256-bit bus, 960 GB/s bandwidth, 360W total graphics power, and 850W PSU recommended, per the Lap 7 research. RTX 5070 Ti uses Blackwell GB203, launched February 2025, with 8,960 CUDA cores, 70 RT cores, 280 Tensor cores, 16GB GDDR7 at 28 Gbps, 256-bit bus, 896 GB/s bandwidth, 300W total graphics power, and 750W PSU, per the 2026-10-31 search (TechRepublic, Pandromeda, Tech4Gamers).

For everyday work, both GPUs are fast. For multitasking, the 5080 offers 20% more cores, against the 5070 Ti, so the 5080 fits 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. HowManyFPS, prices updated 29 October 2026, found the 5080 about 19% faster on average across 100+ games, scoring 70/100 vs 59/100, per the 2026-10-31 search. GadgetScout found the 5070 Ti about 12% slower at 1440p and 13% slower at 4K in aggregate testing, per the 2026-10-31 search. TechPowerUp DLSS testing found the 5080 at 35 FPS vs 31 FPS without upscaling, about 13% ahead, and 62 FPS vs 53 FPS with DLSS Transformer Quality, about 17% ahead, per TechRepublic summary of that test.

For students, both GPUs should handle notes, browsing, documents and light coding easily. For creators, the 5080 should help more in rendering, while the 5070 Ti should help more in value. For developers, both GPUs should handle compilation and local AI, with the 5080 helping more in compute, and the 5070 Ti helping more in efficiency.

Gaming

For gaming, the 5080 wins clearly, with 10,752 CUDA cores, against the 5070 Ti's 8,960 cores. The 5070 Ti offers the same 16GB memory, so it should play games well, but not AAA gaming at the same level. ThePCEnthusiast testing found Forza Horizon 5 at 1440p at 188 FPS on the 5070 Ti vs 205 FPS on the 5080, about 9% ahead, and at 4K about 13% ahead, per the 2026-10-31 search. Watch Dogs: Legion found the 5080 more than 20% ahead at 1440p, 169 FPS vs 138 FPS, per the same source. The Witcher 3 Next Gen was the unusual result, with the 5070 Ti ahead at 1440p in that test, 106 FPS vs 98 FPS, per the same source, so no game is claimed as a universal winner.

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 2026-10-31 search (Pandromeda, RunAIHome), and 16GB memory, so it should handle local AI models well. RTX 5070 Ti offers 1,406 AI TOPS, per the same search, and 16GB memory, so it should handle local AI models well. RunAIHome llama.cpp testing found Llama 2 7B Q4_0 token generation at 182.43 tok/s on the 5070 Ti vs 184.68 tok/s on the 5080, only about 1.2% ahead, while prompt processing was 8,419 tok/s vs 9,487 tok/s, about 12.7% ahead, per the 2026-10-31 search. No controlled side-by-side AI test beyond those cited was reviewed, so no AI winner is claimed beyond the TOPS and token 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 5070 Ti helping more in efficiency.

Display

Display is not a GPU feature, but the outputs differ. Both GPUs offer DisplayPort 2.1 and HDMI 2.1, per the 2026-10-31 search, with the 5070 Ti offering DisplayPort x3 and HDMI 2.1b on some models. For colour work, both GPUs are excellent, with 16GB memory helping in large textures. For gaming, both GPUs are excellent, with DLSS 4 Multi Frame Generation on both. 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 5070 Ti uses 300W total graphics power, per the 2026-10-31 search, with 750W PSU recommended. 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 5070 Ti's fans should be quieter. RTX 5070 Ti uses 300W, 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 5070 Ti should be quieter.

Price

RTX 5080 launched at $999 US, per the Lap 7 research, and £979 UK, per GadgetScout. RTX 5070 Ti launched at $749 US, per the 2026-10-31 search, and £729 UK, per GadgetScout. The launch gap was $250 US, about 33%, per TechRepublic. By October 2026, street prices were well above launch: HowManyFPS listed the 5080 at $1,319.99 vs the 5070 Ti at $999.99, a $320 gap, per the 2026-10-31 search. RunAIHome listed September 2026 street prices at $1,517-$1,799 for the 5080 vs $1,000-$1,200 for the 5070 Ti, per the same search. 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, the 5070 Ti's price is lower, but it includes fewer cores, against the 5080's more cores. For value buyers, the 5070 Ti's lower price is justified; for 4K buyers, the 5080's price is justified by its performance.

Verdict

Buy RTX 5080 if you need 4K headroom and ray tracing, at $999 launch. Buy RTX 5070 Ti if you need value and 1440p, at $749 launch. For most 1440p buyers, the 5070 Ti wins; for most 4K buyers, the 5080 wins.
