Architecture, Features and Performance Tier
Both cards are powered by NVIDIA Blackwell architecture and support DLSS 4, so you get the same modern feature set for upscaling, frame generation, and AI acceleration in games and creative apps. That shared foundation means your decision is less about feature support and more about which performance tier you need for your 1440p monitor and target refresh rate.
The ASUS TUF Gaming GeForce RTX 5080 16GB GDDR7 OC sits a tier above the GIGABYTE GeForce RTX 5070 Ti Gaming OC 16G in the product stack, and owners commonly report that it holds higher average frame rates at 1440p with ray tracing and DLSS enabled. Per the spec sheet, the ASUS card lists an OC mode boost clock of 2730 MHz and a default mode of 2700 MHz, which points to a higher factory tuned clock, while the GIGABYTE card does not list a boost clock in the provided data so you should evaluate it on its Gaming OC positioning and cooler rather than a direct clock comparison.
For 1440p gaming, that tier difference matters most if you play at 165Hz, 240Hz, or with heavy ray tracing where extra headroom keeps you above your refresh target. If you mostly play competitive shooters at 1440p or you use DLSS 4 to stretch performance, the GIGABYTE GeForce RTX 5070 Ti Gaming OC 16G is still a strong 1440p card, but it will have less overhead for future titles than the ASUS TUF Gaming GeForce RTX 5080 16GB GDDR7 OC. You can see how this tier fits among other options in our Graphics Cards archive.
VRAM and Memory Configuration
Memory is one area where these two cards are closely matched on paper. Both are integrated with 16GB of GDDR7, which is plenty for 1440p with high textures, and both should handle current 1440p ultra settings without forcing texture compromises. The GIGABYTE spec sheet explicitly calls out a 256-bit memory interface, while the ASUS sheet lists 16GB GDDR7 without detailing bus width in the provided data.
Because both offer 16GB, you should not choose between them based on capacity alone. Instead, think about how you use VRAM at 1440p. If you mod games, run creative workloads, or keep cards for several years, 16GB gives you comfortable breathing room on either card. For a deeper look at how 16GB cards scale at this resolution, our top RTX 5070 ti cards for 1440p gaming breakdown shows what to expect from this class of GPU.
A practical difference is that neither card offers a VRAM advantage over the other, so your choice should hinge on GPU tier and cooling rather than memory size. If you were hoping one would offer 20GB or 24GB for heavy 4K texture packs, neither is the right choice for that use case, you would need to look at a different class of card entirely.
Power Requirements and PSU Planning
Power planning is where the ASUS TUF Gaming GeForce RTX 5080 16GB GDDR7 OC asks for more careful preparation. Its spec sheet calls for a minimum 850W PSU with a 16-pin 12V-2×6 (12VHPWR) connector and notes you should verify before purchasing. That is a clear signal to budget for a quality ATX 3.x unit with the correct native cable and to leave headroom above the combined draw of your GPU and CPU.
The GIGABYTE GeForce RTX 5070 Ti Gaming OC 16G spec sheet does not list a recommended wattage in the provided data, but it is also a Blackwell card with PCIe 5.0 and 16GB GDDR7, so you should still follow the maker recommended wattage on the product page and use a PSU with appropriate headroom. In general, we recommend you size your PSU so you have comfortable headroom over your system peak, follow the GPU maker guidance, and avoid claims that any single wattage handles every build.
Whichever card you pick, plan your cables and power delivery before you buy. Confirm your PSU has a native 16-pin 12V-2×6 lead or a reliable adapter approved by the manufacturer, route the cable with a gentle bend, and follow the manufacturer mounting instructions with anti-static handling. If your current PSU is older, lower wattage, or lacks the required connector, factor a PSU upgrade into your total build cost, especially with the higher-end pick in September 2026.
Size, Cooling and Case Fit
Physical fit is a concrete differentiator you can verify today. The ASUS TUF Gaming GeForce RTX 5080 16GB GDDR7 OC measures 348mm (13.7 inches) long, occupies 3.6 slots, and weighs 4.3 lbs, and it includes a GPU bracket. Its 3.6-slot design uses a massive fin array with three Axial-tech fans, a protective PCB coating, military-grade components, and a phase-change GPU thermal pad designed to last longer than traditional paste under heavy loads.
The GIGABYTE GeForce RTX 5070 Ti Gaming OC 16G uses the WINDFORCE cooling system and lists PCIe 5.0 support, but the provided data does not include length, slot thickness, or weight. That means you must check the maker page for exact clearance before you order, and you should still measure your case GPU clearance, slot spacing, and front radiator or fan interference. If you are building in a compact mid-tower, the ASUS card length and 3.6-slot thickness will be the harder fit.
Cooling approach also hints at noise and thermal behavior. The ASUS TUF design is explicitly tuned for airflow with its large fin stack and three fans, plus Auto-Extreme manufacturing and GPU Tweak III for thermal controls and monitoring. The GIGABYTE WINDFORCE system is also built for sustained cooling, but without dimensions in the data we cannot compare slot impact directly, so treat case compatibility as a must-check item for both.

Which One Should You Get
Choose the ASUS TUF Gaming GeForce RTX 5080 16GB GDDR7 OC if you want maximum headroom for 1440p high refresh gaming and you have the case and power to support it. It is the better fit when you target 165Hz to 240Hz at 1440p with ray tracing, you want the higher factory boost clocks of 2730 MHz in OC mode and 2700 MHz default, and you can accommodate a 348mm, 3.6-slot, 4.3 lb card with an 850W PSU and 16-pin 12V-2×6 connector. You will also appreciate its rugged TUF reinforcements, protective PCB coating, phase-change thermal pad, and GPU Tweak III controls if you keep cards for years and value durability and monitoring.
Choose the GIGABYTE GeForce RTX 5070 Ti Gaming OC 16G if you want strong 1440p performance with a more practical footprint and lower total build cost. It is the smarter pick when you game at 1440p 144Hz to 165Hz, you want Blackwell and DLSS 4 with 16GB GDDR7 on a 256-bit interface and PCIe 5.0, and you prefer the WINDFORCE cooler without committing to the larger, heavier, and more power demanding premium tier. It also makes sense if you are pairing the GPU with a mid-range CPU and want to allocate more budget to a high quality monitor, storage, or a PSU with proper headroom rather than the top tier GPU alone.
Who Should Skip Both
Both of these cards are not ideal for small form factor builds, low wattage power supplies, or 1080p 60Hz gaming where you would pay for headroom you will not use. If your case cannot clear a long triple-fan card, if your PSU lacks the required 16-pin connector and wattage headroom, or if you need a compact dual-fan model for a tight chassis, this pair is not a good fit and you should consider a smaller, lower power GPU class.
They are also not the right choice if you are building primarily for 4K ultra with heavy ray tracing or for professional workloads that benefit from more than 16GB of VRAM. In those scenarios you are better served by a higher tier card or a workstation oriented option. For most 1440p gamers though, either of these 16GB Blackwell cards is well matched, the question is simply how much headroom and physical size you want to take on.
