GeForce RTX 5070 Mini OC Review in color
Introduction
The Colorful GeForce RTX 5070 Mini OC is a refreshing new take on custom-designed graphics cards from a company that makes its mark with large, high-end graphics card designs. It wants to raise the bar with the amount of graphics processing muscle packed into a card that’s 18 inches long and no more than 2 slots, without requiring liquid cooling. The GeForce RTX 5070 is a performance-class GPU, recommended by NVIDIA for 1440p AAA gaming with ray tracing, although it is possible for this GPU to play in 4K Ultra HD if you know your way around game settings, or you can get into the latest DLSS 4.5 and multi-frame rendering features.
Many custom GeForce graphics card designers have already followed NVIDIA’s lead in designing integrated PCBs for the RTX 5070, with the aim of allowing flow-through cooling solutions where the airflow from one of the three fans flows into the heatsink and exits through a cut in the backplate. The RTX 5070 Mini OC is also different. Where Colorful’s designers diverged was in designing a compact air-cooling solution that uses a tightly packed aluminum fin-stack heatsink with its fins protruding from a cooling fabric cut, which is a reinforcing steel frame rather than a cover, like on NVIDIA Founders Edition cards. This heatsink uses four copper heat pipes that carry heat through an aluminum fin-stack that is ventilated by a single 100 mm card fan. The challenge here is to tame the GPU with a total graphics power of 250 W loaded.
The NVIDIA GeForce RTX 5070 is powered by the latest GeForce Blackwell graphics architecture. It improves on all aspects of the GPU despite the fact that the chips themselves are built on the same NVIDIA 4N innovation platform as the old RTX 40 series. The new CUDA cores come with more IPC and support for Neural Rendering and reprogramming the shader you know with Neural shaders. The new generation of RT cores comes with productivity improvements in ray tracing performance, further reducing the cost of ray tracing in your frame rates, and comes with Mega Geometry optimization, a feature where the geometric details of ray traced objects can be greatly increased (think what tessellation does to poly calculations in raster graphics).
Perhaps Blackwell’s biggest feature update over the old Ada architecture is the support for DLSS Multi Frame Generation, or the ability to draw up to five frames following every frame rendered completely normalized using AI, effectively multiplying frame rates by up to 6 times. This 6x Multi Frame Generation feature was recently announced by NVIDIA as part of its 2026 International CES update. Also announced is DLSS 4.5, a new upscaler that uses an updated Transformer-based AI model that is more accurate than the DLSS 4 released alongside the RTX 50-series, which offers a significant increase in image quality over older versions of DLSS that use convoluted neural networks (CNN) based on top.
The GeForce RTX 5070 is based on the GB205 silicon, which almost replaces it, enabling 48 of the 50 streaming multiprocessors (SM), working on 6,144 CUDA cores, 192 Tensor cores, 48 RT cores, 192 TMUs, and 80 ROPs. The chip also packs 48 MB of L2 cache. NVIDIA used standard GDDR7 memory for this generation. While the memory size and bus width remain unchanged from the previous generation RTX 4070, with its 12 GB across 192-bit; GDDR7 offers a data rate of 28 Gbps, resulting in a 33% increase in memory bandwidth.
The GeForce RTX 5070 Mini OC Colorful is a uniquely designed product that should grab the attention of the SFF gaming PC crowd. Not only is it SFF-Ready as NVIDIA describes it, but it is an extreme GPU integration that some brands even build cards with triple slots. Colorful is asking $760 for this card (based on the Chinese price on JD.com)
