The "Ampere" graphics architecture included inside the previous generation GeForce RTX 30 Series has been significantly improved by NVIDIA's new "Ada Lovelace" graphics architecture in the NVIDIA GeForce RTX “40” Series GPUs. The Lovelace architecture has not only upgraded overall performance with more cores and faster clock speeds, but also dramatically improves ray-tracing performance. The NVIDIA GeForce RTX 4070 is capable of running games at 4K, but it excels at 1440p, where it can push refresh rates over 120 frames per second (fps) in most games. This makes it an excellent option for competitive gamers who want to compete on a fast, high-resolution display.
The GeForce RTX 4070 is equipped with upgraded 3rd generation RT Cores and 4th generation Tensor Cores, as well as lightning fast GDDR6X memory. This GPU and its direct predecessor, the RTX 3070, share a lot of characteristics. Both support 46 raytracing (RT) cores, 184 Tensor cores, 5888 CUDA cores, and 184 texture mapping units (TMUs). They are different because the RTX 4070 has 64 raster operation units (ROPs) and a 192-bit interface. With an HDMI port and 3x DisplayPort connections, it can accommodate up to 4x independent monitors at 120Hz. Although at 240Hz, it can only support 2x 4K monitors or 8K at 60Hz with DSC using DP or HDMI.
Memory
With 12GB of GDDR6X RAM, the RTX 4070 has a 192-bit memory interface running at speeds of 1313 MHz (effectively 21 Gbps). The GPU operates at 1920 MHz with a boost speed of 2475 MHz. This graphics card does not support NVIDIA’s NVLink.
Cooling & Features
The dual-slot NVIDIA RTX 4070 GPU resembles the larger RTX 4080 and RTX 4090 cards, with the exception of its smaller size. On the exterior of the card there are three DisplayPort connections and one HDMI connection. Two fans that are placed at the card's opposing ends with one exposed on each side of the board. This cooling design enables a flow-through system drawing air from the bottom, through the card, and out the case's top. It draws power from 1x 16-pin power connector, with power draw rated at 200 W maximum, or 2x 8-pin connectors. Minimum required system power is listed at 650W.
Summary
The NVIDIA GeForce RTX 4070 GPU raises the bar for both gaming and artistic endeavors. The Ada Lovelace-based graphics card enables 12GB of GDDR6X memory in addition to having 5888 CUDA cores for more realalistic rendering. This VR ready GPU offers users the performance they require to produce their finest work, utilizing 46 RT cores, 184 Tensor cores, 5888 CUDA cores, and 184 TMUs.
