ASRock Radeon RX 9070 Steel Legend OC VS Gigabyte GeForce RTX 5070 Ti Aero OC

At first glance, the clock speed comparison tells an interesting story. The ASRock RX 9070 Steel Legend OC boosts to a higher turbo of 2700 MHz versus the Gigabyte RTX 5070 Ti Aero OC's 2588 MHz, despite starting from a much lower base clock. This wider boost range on the RX 9070 reflects AMD RDNA 4's aggressive dynamic frequency scaling. The RTX 5070 Ti, by contrast, operates within a narrower and more consistent clock window, which can translate to more predictable frame pacing in practice.

In raw throughput metrics, the picture becomes more nuanced. The RX 9070 leads decisively in floating-point performance at 77.41 TFLOPS versus the RTX 5070 Ti's 46.38 TFLOPS — a gap that reflects RDNA 4's architectural efficiency gains. It also wins on pixel fill rate (345.6 GPixel/s vs. 248.4 GPixel/s), backed by more render output units (128 ROPs vs. 96), which benefits high-resolution rendering and anti-aliasing workloads. The RTX 5070 Ti counters with a higher texture rate of 724.6 GTexels/s thanks to its larger TMU count (280 vs. 224), an advantage in texture-heavy scenes. Memory speed also favors the RX 9070 at 2518 MHz vs. 1750 MHz, which improves bandwidth efficiency in memory-constrained workloads.

Overall, the ASRock RX 9070 Steel Legend OC holds a clear edge in compute throughput, pixel output, and memory speed based strictly on these specs. The Gigabyte RTX 5070 Ti Aero OC carves out an advantage only in texture throughput. Both cards support Double Precision Floating Point, making neither a standout for that specific criterion. For users prioritizing raw compute and fill rate performance as shown by these figures, the RX 9070 is the stronger performer in this group.

The ASRock Radeon RX 9070 Steel Legend OC and the Gigabyte GeForce RTX 5070 Ti Aero OC both come with 16GB of VRAM, ensuring substantial memory capacity. The ASRock card uses GDDR6 memory, while the Gigabyte card upgrades to the newer GDDR7. In terms of memory speed, the ASRock card operates at an effective memory speed of 20000 MHz, while the Gigabyte card achieves a faster 28000 MHz. The maximum memory bandwidth of the ASRock is 644.6 GB/s, which is lower than the Gigabyte’s 896 GB/s.

Both products have a memory bus width of 256-bit, ensuring similar data transfer capabilities in terms of bus width. Additionally, both cards support ECC (Error-Correcting Code) memory, providing enhanced reliability.

Both the ASRock Radeon RX 9070 Steel Legend OC and the Gigabyte GeForce RTX 5070 Ti Aero OC support DirectX 12 Ultimate, OpenGL 4.6, and ray tracing, offering similar capabilities for modern gaming and graphical workloads. The ASRock card supports OpenCL version 2.2, while the Gigabyte card features the newer OpenCL version 3.0. Both cards support multi-display technology and 3D, but the Gigabyte card has the added benefit of supporting DLSS (Deep Learning Super Sampling), whereas the ASRock card does not.

For memory and system optimization features, the ASRock card supports AMD SAM (Smart Access Memory), while the Gigabyte card supports Intel Resizable BAR. Neither card has XeSS (XMX) support. Both cards are equipped with RGB lighting for aesthetic customization.

Neither product includes LHR (Lite Hash Rate) technology, which may appeal to users focused on cryptocurrency mining.

Both the ASRock Radeon RX 9070 Steel Legend OC and the Gigabyte GeForce RTX 5070 Ti Aero OC feature 1 HDMI output with HDMI 2.1b support, ensuring compatibility with high-resolution displays and advanced features.
