Gainward GeForce RTX 5070 Phoenix-S GS VS Gigabyte GeForce RTX 5070 Ti Gaming OC

At the heart of the performance gap between these two cards lies a fundamental difference in GPU silicon. The Gigabyte RTX 5070 Ti Gaming OC is built on a significantly larger chip, featuring 8,960 shading units, 280 TMUs, and 96 ROPs compared to the Gainward Phoenix-S's 6,144 shading units, 192 TMUs, and 80 ROPs. This translates directly into raw compute throughput: the 5070 Ti delivers 46.38 TFLOPS of floating-point performance versus 31.6 TFLOPS on the Phoenix-S — a roughly 47% advantage that will be felt in GPU-bound workloads like 4K gaming, ray tracing, and AI-accelerated rendering.

The clock speed story is more nuanced. The Gainward Phoenix-S actually runs a higher base clock at 2,325 MHz versus the 5070 Ti's 2,295 MHz, while the 5070 Ti edges ahead in turbo at 2,588 MHz compared to 2,572 MHz. In practice, these clock differences are negligible — the 5070 Ti's higher texture rate of 724.6 GTexels/s versus 493.8 GTexels/s and pixel rate of 248.4 GPixel/s versus 205.8 GPixel/s are far more impactful, meaning the 5070 Ti can push more geometry and fill more pixels per second regardless of the marginal clock parity. Both cards share identical 1,750 MHz memory speed and double-precision floating-point support, making those points of no differentiation.

The Gigabyte RTX 5070 Ti Gaming OC holds a clear and substantial performance advantage in this group across every compute and throughput metric that matters. The Gainward Phoenix-S is not a slow card, but it represents a different tier of GPU; users prioritizing maximum rendering performance — especially at higher resolutions or with demanding graphical effects — will find the 5070 Ti meaningfully ahead. The Phoenix-S's only nominal wins are its slightly higher base clock and lower chip complexity, which may contribute to efficiency in lightly-threaded scenarios, but those are marginal considerations against a near-50% gap in raw compute.

Both the Gainward GeForce RTX 5070 Phoenix-S GS and the Gigabyte GeForce RTX 5070 Ti Gaming OC feature an effective memory speed of 28000 MHz, so they match in that regard. However, there are differences in memory bandwidth, with the Gainward offering 672 GB/s and the Gigabyte providing a higher 896 GB/s. The Gainward has 12GB of VRAM, while the Gigabyte comes with 16GB, giving it a larger memory capacity.

Both graphics cards use the same GDDR7 memory version, ensuring they have comparable memory technology. The Gainward has a 192-bit memory bus width, whereas the Gigabyte has a wider 256-bit bus width, which could contribute to its higher memory bandwidth and capacity.

Both products support ECC memory, making them suitable for error-checking in specific applications.

Both the Gainward GeForce RTX 5070 Phoenix-S GS and the Gigabyte GeForce RTX 5070 Ti Gaming OC share identical specifications in several key features. They both support DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3, ensuring compatibility with modern graphics and computing APIs. Additionally, both cards support multi-display technology, ray tracing, and 3D, along with DLSS, making them suitable for high-quality gaming and immersive experiences.

Neither card features XeSS (XMX), and both support Intel’s Resizable BAR technology, offering enhanced memory access for compatible systems. Both products also lack LHR (Lite Hash Rate) limitations, which may appeal to users interested in cryptocurrency mining.

In terms of aesthetics and customization, both cards include RGB lighting. Furthermore, both the Gainward and Gigabyte cards can support up to 4 displays simultaneously, making them ideal for multi-monitor setups.

Both the Gainward GeForce RTX 5070 Phoenix-S GS and the Gigabyte GeForce RTX 5070 Ti Gaming OC are equipped with an HDMI output, featuring 1 HDMI port each. Both cards support the HDMI 2.1b version, allowing for high-bandwidth video and audio transmission.

Each graphics card also offers 3 DisplayPort outputs, providing additional options for connecting to compatible displays. Neither of the two cards includes USB-C ports, DVI outputs, or mini DisplayPort outputs, so their connectivity options are limited to HDMI and DisplayPort.

In summary, the port configurations are identical between the two products, offering the same HDMI and DisplayPort options with no additional display outputs available on either card.

Both the Gainward GeForce RTX 5070 Phoenix-S GS and the Gigabyte GeForce RTX 5070 Ti Gaming OC are built on the same GPU architecture, Blackwell, and use the same 5 nm semiconductor size. The Gainward has a Thermal Design Power (TDP) of 250W, while the Gigabyte has a slightly higher TDP of 300W. Both cards are PCI Express 5.0 compatible, ensuring high-speed data transfer between the GPU and the motherboard.

The Gainward has 31,100 million transistors, while the Gigabyte boasts 45,600 million transistors, indicating a more complex and potentially higher-performing GPU. Neither card has air-water cooling, both relying on traditional cooling solutions.

In terms of physical dimensions, the Gainward measures 331.9 mm in width and 127.1 mm in height, while the Gigabyte is slightly larger with a width of 340 mm and a height of 140 mm.
