The RTX 4070’s 12GB should be fine for most games at 1440p, though note that flipping on ray-tracing effects eats heavily into VRAM as well. That said, with games gobbling ever-increasing amounts of VRAM now that the latest console generation (and 16GB of shared memory) are the standard, I’d be nervous about buying a graphics card for 4K gaming with less than 16GB of memory. That goes doubly so given its 12GB memory capacity-a very welcome upgrade over the 8GB that Nvidia’s 70-class remained stuck on since the GTX 1070’s launch in 2016. You had to go all the way down to the $3 to find an Nvidia GPU with a 192-bit bus last generation. Even the already-pandemic-overpriced $6 Ti had a 256-bit bus. Both of those help boost memory performance but I wouldn’t buy this card for 4K gaming-only 1440p.īy contrast, the RTX 3080-which, again, was a higher-tier card that cost $100 less than the 4070 Ti-wielded a 320-bit bus, which is typical for a high-end GPU. The RTX 4070 comes with GDDR6X, faster memory than its predecessor, as well as a much larger L2 cache (36.8K) for keeping more tasks on the GPU itself. As we discussed extensively in the RTX 4070 Ti’s review, Nvidia equipped the AD104 GPU used by both 4070 cards with a surprisingly narrow 192-bit memory bus, which constrains overall memory bandwidth. You don’t really want the GeForce RTX 4070 for 4K gaming anyway-a conclusion that’s supported by Nvidia’s decision to market this GPU around playing games at 100 frames per second at 1440p resolution. The performance gap widens slightly at 4K resolution. This all represents solid advances over the technology inside last generation’s $4 and $5 Ti, though it’s a significant step back from the 4070 Ti’s might-that card runs roughly 15 to 25 percent faster, depending on the game and resolution. Power Connectors: 2x PCIe 8-pin cables (adapter in box) OR 300W or greater PCIe Gen 5 cable.Here’s a look at its core specifications: Nvidia’s $599 GeForce RTX 4070 uses a cut-down version of the 4N “Ada Lovelace” AD104 GPU found in the RTX 4070 Ti.
