Manufacturer description
The ASUS ROG Strix GeForce RTX 3070 Ti OC Edition is a factory-overclocked graphics card built on NVIDIA's Ampere architecture. It pairs 8GB of GDDR6X memory with a PCIe 4.0 interface, which suits high-refresh 1440p gaming and ray-traced titles. Ampere Streaming Multiprocessors deliver 2X the FP32 throughput of the previous generation. The 2nd-gen RT Cores double ray-tracing throughput and can run ray tracing and shading at the same time. The 3rd-gen Tensor Cores drive DLSS, which raises frame rates and supports output up to 8K. For display outputs you get HDMI 2.1 and DisplayPort 1.4a, so…
SpecPicks Verdict
SpecPicks scored ASUS ROG Strix NVIDIA GeForce RTX 3070 Ti OC Edition Gaming Graphics… using a rating × review-volume × price-fit model applied to our editorial and benchmark analysis across the graphics cards category. ASUS's graphics cards lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for graphics cards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
How much VRAM does the ASUS ROG Strix RTX 3070 Ti OC have?
It has 8GB of GDDR6X memory. That handles 1440p gaming well, but very demanding 4K texture settings or large local AI models can go past 8GB.
Will the ROG Strix RTX 3070 Ti fit in my case?
The card is 2.9 slots thick, so it takes up nearly three expansion slots. Check your case's GPU clearance and slot spacing against the dimensions on the ASUS product page before you buy.
Does the ASUS RTX 3070 Ti OC support HDMI 2.1 and ray tracing?
Yes. It has HDMI 2.1 and DisplayPort 1.4a outputs. Its 2nd-gen RT Cores provide hardware ray tracing and can run ray tracing and shading at the same time.
Can I use this card in a PCIe 3.0 motherboard?
The card uses a PCIe 4.0 interface, and PCIe is backward compatible, so it will run in a PCIe 3.0 x16 slot at PCIe 3.0 bandwidth. Check the ASUS listing for your board's specific compatibility.
What warranty comes with the ASUS ROG Strix RTX 3070 Ti OC?
The listing states a 3-year warranty. Check ASUS's warranty page for current coverage terms and registration requirements in your region.
