ASRock Radeon RX 9070 Steel Legend OC VS Asus ROG Strix GeForce RTX 5070 Ti

At first glance, the clock speed story here is split: the RTX 5070 Ti runs a higher base clock at 2295 MHz, suggesting a more consistently elevated operating frequency, while the RX 9070 Steel Legend OC swings far harder at peak with a turbo of 2700 MHz versus the 5070 Ti's 2452 MHz. In practice, base clock matters for sustained workloads like compute tasks and long renders, while turbo headroom determines burst performance in shorter gaming scenarios. Neither card dominates this metric outright, but the RX 9070's wider gap between base and boost hints at a more aggressive dynamic frequency scaling strategy.

Where the comparison becomes striking is in raw compute throughput. The RX 9070 delivers 77.41 TFLOPS of floating-point performance — nearly 76% more than the 5070 Ti's 43.94 TFLOPS — despite having far fewer shading units (3584 vs. 8960). This apparent paradox is architectural: AMD's RDNA 4 design extracts significantly more compute per clock cycle from each unit. The RX 9070 also holds a commanding lead in pixel fill rate (345.6 vs. 235.4 GPixel/s) and memory speed (2518 vs. 1750 MHz), both of which translate directly to sharper rasterization throughput and faster texture data delivery in high-resolution gaming. The 5070 Ti counters with a higher texture rate (686.6 vs. 604.8 GTexels/s) owing to its larger TMU count (280 vs. 224), which can benefit texture-heavy scenes, though the RX 9070's overall bandwidth advantage partially offsets this edge.

On balance, the ASRock Radeon RX 9070 Steel Legend OC holds a clear performance edge within this spec group. Its lead in floating-point compute, pixel throughput, and memory speed are not marginal — they represent substantial real-world advantages in rasterized rendering workloads. The RTX 5070 Ti's superior texture rate and higher shading unit count are notable, but do not overcome the RX 9070's aggregate compute advantage as reflected in these figures. Both cards support Double Precision Floating Point, making neither uniquely suited for professional compute on that criterion alone.

The ASRock Radeon RX 9070 Steel Legend OC features an effective memory speed of 20000 MHz, while the Asus ROG Strix GeForce RTX 5070 Ti has a faster effective memory speed of 28000 MHz. The maximum memory bandwidth of the RX 9070 is 644.6 GB/s, which is lower than the RTX 5070 Ti's higher bandwidth of 896 GB/s.

Both graphics cards are equipped with 16GB of VRAM, so they share the same memory size. They also both use a 256-bit memory bus width, which is identical for both models. Additionally, both cards support ECC memory, confirming that they are capable of error correction.

In terms of GDDR version, the RX 9070 uses GDDR6, while the RTX 5070 Ti is equipped with the newer GDDR7, which typically offers improved performance and efficiency.

Both the ASRock Radeon RX 9070 Steel Legend OC and the Asus ROG Strix GeForce RTX 5070 Ti support DirectX 12 Ultimate and OpenGL 4.6, ensuring compatibility with modern gaming and rendering technologies. However, the RX 9070 supports OpenCL version 2.2, while the RTX 5070 Ti is equipped with OpenCL version 3, offering a slightly newer specification.

Both cards support multi-display technology, ray tracing, and 3D rendering, making them suitable for high-end gaming and professional workloads. The RX 9070 does not support DLSS or XeSS (XMX), whereas the RTX 5070 Ti supports DLSS, which could be advantageous for performance in supported games.

Regarding other features, the RX 9070 uses AMD SAM (Smart Access Memory) for optimized performance with compatible AMD platforms, while the RTX 5070 Ti supports Intel's Resizable BAR technology. Both cards lack LHR (Lite Hash Rate) limitations, feature RGB lighting, and support up to four displays.

Both the ASRock Radeon RX 9070 Steel Legend OC and the Asus ROG Strix GeForce RTX 5070 Ti feature an HDMI output with HDMI 2.1b support. However, the RX 9070 has 1 HDMI port, while the RTX 5070 Ti includes 2 HDMI ports, providing slightly more flexibility in multi-display setups.

Both cards are equipped with 3 DisplayPort outputs, and neither card includes USB-C ports, DVI outputs, or mini DisplayPort outputs.

The ASRock Radeon RX 9070 Steel Legend OC is built on the RDNA 4.0 architecture, while the Asus ROG Strix GeForce RTX 5070 Ti utilizes the Blackwell architecture. Both cards use a 5 nm semiconductor size, ensuring modern manufacturing processes.

In terms of power consumption, the RX 9070 has a Thermal Design Power (TDP) of 220W, which is lower than the RTX 5070 Ti’s 300W TDP. Both cards support PCIe version 5, ensuring high bandwidth for data transfer.

For physical dimensions, the RX 9070 is 298 mm in width and 131 mm in height, while the RTX 5070 Ti is larger at 332 mm in width and 147.3 mm in height. Neither card includes air-water cooling systems, and both are equipped with a large number of transistors, with the RX 9070 featuring 53900 million transistors, and the RTX 5070 Ti featuring 45600 million.
