ASRock Radeon RX 9070 Steel Legend OC VS ASRock Radeon RX 9070 XT Steel Legend

At the core of the performance comparison, the RX 9070 XT Steel Legend holds a structural advantage in raw compute resources: it packs 4096 shading units and 256 TMUs against the Steel Legend OC's 3584 shaders and 224 TMUs. More shading units translate directly to greater parallelism — the ability to process more graphical workloads simultaneously — while additional TMUs accelerate texture-heavy scenes. The XT also runs at a higher GPU turbo clock of 2970 MHz versus 2700 MHz, which compounds its shader advantage: more units running faster means it pulls further ahead under sustained load. This is reflected in the texture throughput, where the XT delivers 760.3 GTexels/s compared to 604.8 GTexels/s on the OC — a roughly 26% lead that would be noticeable in demanding, texture-rich environments.

Pixel fillrate tells a similar story: the XT's 380.2 GPixel/s versus the OC's 345.6 GPixel/s, with both cards sharing an identical 128 ROPs count. Since ROPs are the bottleneck for pixel output, the XT squeezes more throughput from the same ROP count purely through its clock speed advantage. One area where the data diverges from this pattern is floating-point performance: the Steel Legend OC is listed at 77.41 TFLOPS versus the XT's 48.66 TFLOPS. Given that the OC has fewer shaders and lower clocks across the board, this figure stands in contrast to the other metrics and should be weighed cautiously alongside them. Both cards share the same 2518 MHz memory speed and both support Double Precision Floating Point, so neither holds an edge in memory bandwidth rate or professional compute workload compatibility.

Overall, the RX 9070 XT Steel Legend has a clear structural edge for gaming and graphics workloads: more shading units, higher TMU count, faster clocks, and superior pixel and texture throughput all point in its favor. The RX 9070 Steel Legend OC counters only with its notably higher TFLOPS figure, which is an outlier relative to the rest of its spec sheet. Users prioritizing consistent, well-rounded rasterization performance — especially in texture-heavy games — will find the XT the stronger performer based on the available data.

When it comes to memory, the two cards are in complete lockstep. Both the Steel Legend OC and the XT Steel Legend are equipped with 16GB of GDDR6 running on a 256-bit bus at an effective speed of 20000 MHz, yielding identical peak bandwidth of 644.6 GB/s. That bandwidth figure is substantial — it means the GPU can move large volumes of texture, geometry, and frame data quickly enough to keep pace with modern high-resolution workloads, including 4K gaming and content creation pipelines with large assets.

The shared 256-bit bus width is worth highlighting as a design choice: it sits in the sweet spot for this performance tier, wide enough to sustain high throughput without the power and cost overhead of a 320-bit or wider interface. Meanwhile, support for ECC (Error-Correcting Code) memory on both cards adds a layer of data integrity useful in professional or semi-professional compute workloads, where silent memory errors would be costly — though for pure gaming use it has negligible impact.

This group is a straightforward tie: every single memory specification is shared between the two cards, from capacity to speed to bus architecture. Buyers choosing between them can set memory performance entirely aside — neither card holds any advantage here, and the decision should rest on other specification groups entirely.

Feature parity is total between these two cards. Both support DirectX 12 Ultimate — the current gold standard for modern gaming, enabling hardware-accelerated ray tracing, mesh shaders, and variable rate shading — and both back it up with confirmed ray tracing support, meaning neither card cuts corners on the API features that matter most for next-generation titles. OpenGL 4.6 and OpenCL 2.2 coverage is identical as well, keeping both cards equally capable for creative and compute workloads beyond gaming.

On the upscaling front, the picture is consistent: both cards carry FSR4 and neither supports DLSS or XeSS (XMX). FSR4 is AMD's latest spatial and AI-assisted upscaling technology, and having it on both cards means users get the same quality uplift in supported titles regardless of which model they choose. The absence of DLSS is expected — that remains exclusive to NVIDIA hardware — and the lack of XeSS (XMX) is similarly unsurprising given these are AMD products. Both also support AMD SAM (Smart Access Memory), which can improve performance when paired with a compatible AMD Ryzen platform by allowing the CPU to access the full GPU frame buffer.

With support for up to 4 simultaneous displays, RGB lighting, and no LHR restrictions on either card, there is genuinely nothing to separate the two here. This group is a clean tie across every data point, and feature set should play no role in the buying decision between the Steel Legend OC and the XT Steel Legend.

Both cards share an identical port configuration: 1 HDMI 2.1b output and 3 DisplayPort outputs, giving users four total display connections — which aligns with the four-display limit noted in the Features group. HDMI 2.1b is the latest revision of the HDMI standard, supporting high refresh rates at 4K and beyond, making it well-suited for modern gaming monitors and televisions alike. The three DisplayPort outputs provide additional flexibility for multi-monitor productivity setups or daisy-chaining compatible displays.

Neither card includes USB-C, DVI, or mini DisplayPort outputs. The absence of USB-C is worth noting for users who own USB-C or Thunderbolt-connected monitors, as they would need an active adapter — but this is a common trade-off at this product tier and affects both cards equally. The lack of DVI is unremarkable given that standard has been largely phased out of modern GPU designs.

This group is another complete tie. The port layout is identical in every respect — connector types, counts, and standards — so display connectivity should not factor into the choice between the Steel Legend OC and the XT Steel Legend.

Sharing the same RDNA 4.0 architecture and PCIe 5.0 interface, both cards are built on the same generational foundation — but a closer look reveals meaningful differences beneath the surface. The most striking divergence is in Thermal Design Power: the Steel Legend OC operates at 220W while the XT Steel Legend is rated at 304W, a gap of 84W or roughly 38% more power demand. In practical terms, this means the XT requires a more capable PSU, produces more heat under load, and will likely run louder as its cooler works harder to dissipate that additional thermal output.

Interestingly, the two cards are listed with different process nodes — 5 nm for the Steel Legend OC and 4 nm for the XT — yet both carry an identical transistor count of 53,900 million. A smaller node generally allows for greater efficiency or higher clock headroom at a given power envelope, which is consistent with the XT's higher turbo clocks seen in the Performance group. Despite this process advantage, the XT's significantly higher TDP shows that the extra shader count and clock speed come at a real power cost. Physical dimensions are exactly the same — 298 mm × 131 mm — so both cards will fit identically in any compatible chassis, with no installation trade-offs between them.

For this group, the Steel Legend OC holds a clear practical edge in power efficiency: it draws substantially less power while fitting in the same physical footprint, making it the more suitable choice for builds with tighter PSU headroom, smaller cases with restricted airflow, or users prioritizing lower running costs. The XT's higher TDP is the price of its performance uplift, and buyers should factor in both PSU capacity and thermal management before committing.
