Gainward GeForce RTX 5070 Ti Phoenix VS Inno3D GeForce RTX 5070 Twin X2 OC

At first glance, the Inno3D RTX 5070 Twin X2 OC appears to have the clock speed edge, running a base of 2325 MHz and boosting to 2542 MHz versus the Gainward Phoenix's 2295 / 2452 MHz. However, raw clock speed tells only part of the story — the underlying GPU architecture and core counts are what ultimately drive throughput, and here the gap is substantial.

The Gainward RTX 5070 Ti Phoenix carries significantly more silicon: 8960 shading units, 280 TMUs, and 96 ROPs against the Twin X2 OC's 6144 / 192 / 80 respectively. That wider execution footprint translates directly into real-world output — the Phoenix delivers 43.94 TFLOPS of floating-point performance and a texture rate of 686.6 GTexels/s, compared to 31.24 TFLOPS and 488.1 GTexels/s for the Inno3D. In practical terms, this means the Phoenix can push considerably more geometry and shading work per frame, which matters most in demanding rasterized titles and GPU compute workloads. The higher ROP count also gives it a meaningful pixel fill-rate advantage (235.4 vs 203.4 GPixel/s), benefiting high-resolution rendering and anti-aliasing.

Both cards share identical 1750 MHz memory speed and both support Double Precision Floating Point, so those factors are a wash. The clear winner in this group is the Gainward RTX 5070 Ti Phoenix — despite slightly lower boost clocks, its broader GPU with far more compute resources gives it a decisive and consistent performance advantage across virtually every workload.

The Gainward GeForce RTX 5070 Ti Phoenix and Inno3D GeForce RTX 5070 Twin X2 OC have similar memory specifications, but there are a few key differences. Both cards use GDDR7 memory and feature an effective memory speed of 28000 MHz. However, the Gainward model has a larger VRAM capacity of 16GB, compared to the Inno3D's 12GB. This difference in memory size may impact performance in memory-intensive applications.

When it comes to memory bandwidth, the Gainward offers a higher maximum memory bandwidth of 896 GB/s, while the Inno3D's bandwidth is 672 GB/s, providing a noticeable gap between the two in terms of data transfer speed.

Both products support ECC (Error-Correcting Code) memory, ensuring more reliable operation by detecting and correcting errors in the memory. The Gainward has a 256-bit memory bus width, whereas the Inno3D has a 192-bit memory bus width, which also contributes to the difference in memory bandwidth between the two models.

The Gainward GeForce RTX 5070 Ti Phoenix and Inno3D GeForce RTX 5070 Twin X2 OC share a nearly identical set of features. Both cards support DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, making them compatible with a wide range of modern software. They also support multi-display technology, ray tracing, and 3D, providing an immersive experience for gaming and content creation.

Additionally, both products support DLSS (Deep Learning Super Sampling), a technology designed to improve performance and image quality in compatible games. Neither card supports XeSS (XMX), and both are equipped with Intel Resizable BAR support, which enhances memory management in supported systems. Both also feature RGB lighting, adding a customizable aesthetic to the cards.

In terms of supported displays, both cards can handle up to four displays simultaneously. They also do not have LHR (Lite Hash Rate), meaning they are not limited in performance for cryptocurrency mining tasks. Overall, the two products are very closely matched in features, with no notable differences between them in this category.

The Gainward GeForce RTX 5070 Ti Phoenix and Inno3D GeForce RTX 5070 Twin X2 OC are identical in terms of their port configurations. Both cards feature one HDMI output, which supports the HDMI 2.1b version, and three DisplayPort outputs. Neither card includes USB-C ports, DVI outputs, or mini DisplayPort outputs. Therefore, in terms of connectivity, the two products offer the same options and capabilities, with no notable differences between them.

Both cards support the latest HDMI standard (HDMI 2.1b), providing compatibility with high-bandwidth displays and allowing for advanced features like higher refresh rates and better resolutions.

The Gainward GeForce RTX 5070 Ti Phoenix and Inno3D GeForce RTX 5070 Twin X2 OC share the same GPU architecture, Blackwell, and both use a 5 nm semiconductor size. However, they differ in a few key areas. The Gainward model has a higher Thermal Design Power (TDP) of 300W, compared to the Inno3D's 250W, which indicates the Gainward may generate more heat under load and require better power delivery.

Both cards support PCI Express (PCIe) version 5, ensuring high-speed data transfer between the GPU and the motherboard. The Gainward card has 45.6 billion transistors, while the Inno3D model has fewer, with 31.1 billion transistors. This difference could suggest a higher level of complexity in the Gainward’s design.

In terms of physical dimensions, the Gainward card is larger, measuring 331.9 mm in width and 133.1 mm in height, while the Inno3D is more compact at 250 mm in width and 116 mm in height. Both cards lack air-water cooling systems, which may impact cooling strategies when considering case airflow.
