ASRock Radeon RX 9070 XT Steel Legend VS Sapphire Pure Radeon RX 9070 XT

At their core, the ASRock Steel Legend and the Sapphire Pure are built on the same GPU silicon: identical base clocks of 1660 MHz, the same 4096 shading units, 256 TMUs, 128 ROPs, and matched memory speeds of 2518 MHz. This means their theoretical throughput ceiling is set by one variable alone — the GPU turbo (boost) clock — which is where the two cards begin to diverge.

The Sapphire Pure reaches a higher boost of 3010 MHz versus the Steel Legend's 2970 MHz, a difference of 40 MHz or roughly 1.3%. Modest as that sounds, it propagates consistently across every derived performance metric: the Pure leads in floating-point performance (49.32 TFLOPS vs 48.66 TFLOPS), texture throughput (770.6 GTexels/s vs 760.3 GTexels/s), and pixel fill rate (385.3 GPixel/s vs 380.2 GPixel/s). In practice, a ~1.3% clock advantage will rarely produce a perceptible fps difference in real workloads, but it does indicate the Sapphire Pure ships with a slightly more aggressive factory tune.

Edge: Sapphire Pure — it holds a consistent, if narrow, lead across all performance metrics purely due to its higher boost clock. Both cards support Double Precision Floating Point, making neither uniquely advantaged for compute tasks. For users choosing strictly on peak theoretical throughput, the Pure has the upper hand, but the gap is small enough that thermal behavior, power delivery, and real-world sustained clocks will matter far more than the spec sheet alone.

When two cards share every single memory specification, the comparison becomes straightforward: the Steel Legend and the Sapphire Pure are in complete parity here. Both feature 16GB of GDDR6 running at an effective 20000 MHz across a 256-bit bus, yielding identical peak bandwidth of 644.6 GB/s. There is nothing on the memory spec sheet that separates them.

That said, these shared numbers are worth contextualizing. A 256-bit bus paired with fast GDDR6 delivers bandwidth that comfortably supports high-resolution textures and large frame buffers at 1440p and 4K. The 16GB VRAM allocation is particularly relevant for modern titles and creative workloads where texture assets and scene complexity are growing rapidly — neither card will feel constrained in the near term. ECC memory support on both is a minor but meaningful bonus for users doing precision compute tasks, adding error-correction capability without any trade-off.

Verdict: Dead tie. Every memory metric is identical across both cards. Choosing between them on memory alone is impossible — buyers should weigh other spec groups or factors like cooling, acoustics, and pricing instead.

Feature parity is total between these two cards. Both support DirectX 12 Ultimate and ray tracing, placing them fully in the current generation of GPU feature sets. Equally important for AMD users is shared support for FSR4 — AMD's latest upscaling technology — which provides a meaningful image quality and performance uplift in supported titles, effectively replacing the need for NVIDIA's DLSS (which neither card supports, as expected for AMD hardware).

AMD SAM (Smart Access Memory) is present on both, allowing a compatible AMD CPU and motherboard to unlock the full VRAM for the processor — a feature that can yield tangible frame rate improvements in SAM-supported games. Neither card carries LHR (Lite Hash Rate) restrictions, and both top out at 4 supported displays, which covers virtually all multi-monitor use cases. RGB lighting is also confirmed on both, though its relevance is purely aesthetic.

Verdict: Complete tie. Not a single feature differentiates the Steel Legend from the Sapphire Pure in this category. Buyers who prioritize software capabilities, API support, or display connectivity will find no reason to prefer one over the other based on features alone.

Both cards offer four total display outputs and share the same HDMI 2.1b standard, which supports 4K at high refresh rates and 8K output — so the version parity means no difference in display capability per port. The divergence lies entirely in how those four slots are allocated: the Steel Legend goes 1 HDMI + 3 DisplayPort, while the Sapphire Pure opts for 2 HDMI + 2 DisplayPort.

This distinction is more meaningful than it first appears. Users running multiple monitors via HDMI — common with TVs, capture devices, or older displays that lack DisplayPort — will find the Sapphire Pure's dual-HDMI layout more accommodating without needing adapters. Conversely, users with a DisplayPort-heavy setup, such as three high-refresh-rate gaming monitors, will prefer the Steel Legend's three DisplayPort outputs, which can drive that configuration natively.

Edge: depends on use case — neither layout is objectively superior, but the Sapphire Pure better serves mixed or HDMI-centric setups, while the Steel Legend is the stronger fit for DisplayPort-dominant multi-monitor configurations. Buyers should map their specific display connections before deciding.

Sharing the same RDNA 4.0 architecture, 4nm process node, and identical transistor count, both cards are cut from the same silicon cloth — so the interesting story here is in how each board partner has chosen to implement it. Two numbers stand out: power draw and physical size.

The Sapphire Pure carries a 317W TDP versus the Steel Legend's 304W — a 13W difference that likely reflects the Pure's higher boost clock (as seen in the Performance group) requiring more headroom. Neither figure is alarming for this GPU tier, but the Steel Legend's lower TDP means marginally less heat generated and slightly lower peak power demands on the PSU, which can matter in thermally constrained or tighter-budget builds. On dimensions, the two cards diverge in an interesting way: the Steel Legend is shorter in length (298mm vs 320mm) but taller (131mm vs 120.3mm). The Pure's extra 22mm in length could create clearance issues in more compact cases, while the Steel Legend's greater height is rarely a concern since most cases accommodate standard dual-slot heights easily.

Edge: ASRock Steel Legend on general hardware practicality — its lower TDP and shorter length make it the more case-friendly option, particularly for builds where PSU overhead or chassis space are limiting factors. The Sapphire Pure's higher power budget is the trade-off it makes for its marginally higher clock speeds.
