This article covers ASUS TUF Gaming NVIDIA® GeForce RTX™ 3070 搭載ビデオカード OC Edition 8GB GDDR6（LHR版） TUF-RTX3070-O8G-V2-GAMING.

Overview

The ASUS TUF Gaming GeForce RTX 3070 OC Edition 8GB GDDR6 (LHR) is a mid-high range graphics card built on NVIDIA's Ampere architecture. With 5,888 CUDA cores, a boost clock of 1845 MHz, and 8GB of GDDR6 memory on a 256-bit interface running at 14 Gbps, this card delivers excellent 1440p gaming performance and can handle light 4K gaming as well. What sets this model apart is the TUF Gaming series' emphasis on durability and thermal management. The card features Axial-tech fans with dual ball bearings, rated for up to twice the lifespan of sleeve bearing designs. The center fan spins in the opposite direction to reduce turbulence, improving overall airflow efficiency across the heatsink. As an LHR (Lite Hash Rate) variant, this GPU is specifically targeted at gamers rather than cryptocurrency miners. It occupies a sweet spot in the market: more affordable than an RTX 3080, yet significantly more powerful than an RTX 3060, making it a balanced choice for enthusiasts who want high frame rates without breaking the bank.

Compatibility Guide

The ASUS TUF Gaming RTX 3070 OC Edition uses a PCI Express 4.0 x16 interface and is backward compatible with PCIe 3.0 slots. However, to fully utilize its bandwidth, a PCIe 4.0-capable motherboard is recommended. The card requires two 8-pin PCIe power connectors, so your power supply should be rated at least 650W, with 750W or higher being a safer choice for systems with high-end CPUs. Physical dimensions are approximately 29.99 x 14.00 x 5.34 cm, and the card occupies 2.7 expansion slots. While it fits most standard ATX cases, users with smaller MicroATX or Mini-ITX builds should carefully measure available GPU clearance and slot width before purchasing.

Product Info

The ASUS TUF Gaming RTX 3070 OC Edition (model TUF-RTX3070-O8G-V2-GAMING) launched in mid-2021 and remains widely available through major retailers. As of September 2026, the typical street price on Japan is around ¥78,000. This OC Edition comes with a factory overclock: boost clock set to 1845 MHz and gaming mode at 1815 MHz, both higher than NVIDIA's reference specifications. ASUS backs this card with a standard 3-year warranty (terms may vary by region and retailer). It is sold through Japan, major PC component stores, and electronics retailers. The card is positioned as a mid-high tier GPU, offering a strong balance of price and performance for gamers who want more than entry-level but don't need flagship-level power.

Best Use Cases

1440p high-refresh-rate gaming: This is the card's natural habitat. It can comfortably push 100+ fps in most modern titles at 1440p with high to ultra settings. Games like Call of Duty, Apex Legends, and Cyberpunk 2077 (with DLSS) run smoothly. Users targeting 4K 60 fps in demanding titles should consider stepping up to an RTX 3080 or RTX 4070. Content creation on a budget: With 5,888 CUDA cores and 8GB VRAM, this GPU handles video editing in Premiere Pro, 3D rendering in Blender, and light AI workloads reasonably well. It's a solid choice for a dual-purpose gaming and creative workstation. However, for heavy 8K video or large-scale machine learning, the 8GB VRAM may become a bottleneck. * First-time high-end PC builder: The RTX 3070 offers excellent price-to-performance ratio for someone building their first serious gaming PC. It's powerful enough to last several years without feeling obsolete, yet not as expensive as flagship models. Budget-conscious builders might also consider the RTX 4060 or RTX 3060 as alternatives.

Things to Consider

Because this is an LHR variant, cryptocurrency mining performance is artificially limited to roughly half the hash rate of the non-LHR version. This has zero impact on gaming or creative workloads, but if you're buying used, verify the model number suffix (V2 indicates LHR) to avoid confusion. While the card comes with a factory overclock, manual overclocking headroom is modest. The ASUS GPU Tweak II utility allows fine-tuning of clocks and fan curves, but extreme overclocking enthusiasts would be better served by higher-tier cards like the RTX 3080 or RTX 4070. Power supply requirements are non-trivial: two 8-pin connectors mean older or lower-wattage PSUs may need an upgrade. Additionally, the 2.7-slot thickness makes multi-GPU setups or Mini-ITX builds impractical. Always check your case's GPU length and slot clearance before buying. ## FAQ
Q: Should I choose an RTX 3070 or an RTX 4060? A: The RTX 3070 generally offers higher raw rasterization performance, while the RTX 4060 benefits from a newer architecture, lower power consumption, and DLSS 3 support. For ray-tracing-heavy games or power efficiency, go with the RTX 4060. For traditional performance-focused gaming, the RTX 3070 is the stronger pick. Q: Can this card handle 4K gaming? A: Yes, but with compromises. You'll need to lower settin
