Gigabyte GeForce RTX 5090 Gaming OC VS Inno3D GeForce RTX 5070 Ti X3 OC

At first glance, the Inno3D RTX 5070 Ti X3 OC appears competitive on clock speeds: its base GPU clock of 2295 MHz actually exceeds the Gigabyte RTX 5090 Gaming OC's 2017 MHz. However, the 5090 Gaming OC surges ahead under sustained load with a higher turbo of 2550 MHz versus the 5070 Ti's 2482 MHz. This means the 5090 not only closes the gap at peak but surpasses it where it matters most — under heavy gaming or rendering workloads.

The real performance story, though, is in the execution resources. The RTX 5090 Gaming OC fields 21,760 shading units, 680 TMUs, and 176 ROPs — roughly 2.4×, 2.4×, and 1.8× more than the 5070 Ti X3 OC's 8,960 / 280 / 96 respectively. These aren't marginal differences; they translate directly into throughput: the 5090 delivers 111 TFLOPS of floating-point performance and a texture rate of 1,734 GTexels/s, compared to the 5070 Ti's 44.48 TFLOPS and 695 GTexels/s — approximately 2.5× the compute and texturing muscle. Pixel fill rate follows suit at 448.8 GPixel/s versus 238.3 GPixel/s, meaning the 5090 can push far more pixels per second, which is especially impactful at 4K and beyond. GPU memory speed is identical at 1750 MHz for both, and both support Double Precision Floating Point, making neither card uniquely advantaged for DPFP workloads on that front alone.

The verdict is unambiguous: the Gigabyte RTX 5090 Gaming OC holds a commanding performance advantage across every meaningful throughput metric in this group. The 5070 Ti X3 OC's higher base clock is a minor footnote against the 5090's overwhelming lead in shader count, compute performance, and rasterization capacity. Users prioritizing raw rendering power — whether for high-refresh 4K gaming, creative workloads, or AI inference — will find the 5090 decisively ahead.

The Gigabyte GeForce RTX 5090 Gaming OC and the Inno3D GeForce RTX 5070 Ti X3 OC have several differences in their memory specifications. Both products feature an effective memory speed of 28000 MHz and are equipped with GDDR7 memory, but their other memory characteristics differ significantly. The RTX 5090 has a much larger VRAM size of 32GB, while the RTX 5070 Ti offers 16GB of VRAM.

Additionally, the maximum memory bandwidth of the RTX 5090 is considerably higher at 1790 GB/s, compared to the RTX 5070 Ti's 896 GB/s. The memory bus width also varies, with the RTX 5090 utilizing a 512-bit bus width, while the RTX 5070 Ti uses a narrower 256-bit bus width.

Both products support ECC (Error-Correcting Code) memory, ensuring improved data integrity, which is common to both cards.

Both the Gigabyte GeForce RTX 5090 Gaming OC and the Inno3D GeForce RTX 5070 Ti X3 OC share several key features, with no significant differences in DirectX, OpenGL, or OpenCL versions. Both cards support DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3. Additionally, they both support multi-display technology, ray tracing, 3D, and DLSS. They also feature Intel Resizable BAR, with no support for AMD SAM, and neither card has LHR (Lite Hash Rate) restrictions.

One noticeable difference is that the RTX 5090 includes RGB lighting, while the RTX 5070 Ti does not. Both cards support up to four displays, making them suitable for multi-monitor setups. Lastly, both GPUs do not feature XeSS (XMX) support.

The ports available on the Gigabyte GeForce RTX 5090 Gaming OC and the Inno3D GeForce RTX 5070 Ti X3 OC are identical. Both cards include one HDMI 2.1b output, with no difference in HDMI version. Each card also offers three DisplayPort outputs, but neither features USB-C, DVI, or mini DisplayPort outputs.

Overall, the port configuration for both products is the same, with no variations between the two in terms of available outputs.

Both the Gigabyte GeForce RTX 5090 Gaming OC and the Inno3D GeForce RTX 5070 Ti X3 OC are based on the Blackwell GPU architecture and use a 5 nm semiconductor size. Both also support PCI Express version 5. However, the RTX 5090 has a significantly higher thermal design power (TDP) of 575W, compared to the RTX 5070 Ti’s 300W TDP.

The number of transistors also differs between the two cards, with the RTX 5090 containing 92200 million transistors, while the RTX 5070 Ti has 45600 million transistors. Both products feature standard air cooling, with no air-water cooling solutions provided.

In terms of physical dimensions, the RTX 5090 is larger, measuring 342 mm in width and 152 mm in height, compared to the RTX 5070 Ti’s smaller size of 300 mm in width and 116 mm in height.
