PowerColor Hellhound Radeon RX 9070 VS PowerColor Reaper Radeon RX 9070

At their core, both the Hellhound and the Reaper share the same fundamental GPU architecture: identical base clocks of 1330 MHz, the same 3584 shading units, 224 TMUs, 128 ROPs, and matched memory speeds of 2518 MHz. This means the two cards start from the same silicon foundation, and any performance gap between them comes down entirely to how far each card is willing to push the GPU under boost conditions.

That gap is defined by the turbo clock: the Hellhound boosts to 2590 MHz versus the Reaper's 2520 MHz — a difference of 70 MHz, or roughly 2.8%. This modest but consistent advantage flows directly into every compute-derived metric. The Hellhound delivers 37.13 TFLOPS of floating-point throughput against the Reaper's 36.13 TFLOPS, a pixel rate of 331.5 GPixel/s versus 322.6 GPixel/s, and a texture rate of 580.2 GTexels/s versus 564.5 GTexels/s. In real-world terms, a ~1 TFLOP difference at this performance tier is unlikely to be felt as a dramatic framerate swing, but it does represent a consistently higher performance ceiling — particularly relevant in sustained GPU-bound workloads like ray tracing, compute tasks, or heavily tessellated scenes.

The Hellhound holds a clear but incremental edge in this group. Both cards are equally capable at the hardware level — same ROPs, same shading units, same memory bandwidth potential — but the Hellhound's higher factory boost clock means it consistently extracts more from the shared silicon. Buyers who prioritize peak performance out of the box, without manual overclocking, will find the Hellhound the stronger choice in this category.

When it comes to memory, the Hellhound and the Reaper are carbon copies of each other. Both cards carry 16GB of GDDR6 across a 256-bit bus, running at an effective speed of 20000 MHz and delivering 644.6 GB/s of peak memory bandwidth. There is not a single differentiating data point in this category.

The shared specification set is nonetheless a strong one. A 256-bit bus paired with 20 Gbps GDDR6 is a well-balanced configuration for a card at this tier — wide enough to avoid bandwidth bottlenecks in high-resolution texturing and modern rendering pipelines, while 16GB of VRAM is increasingly important as games and creative workloads push beyond what 8GB or 12GB cards can comfortably handle. ECC memory support is an added bonus, providing error-correction capabilities that benefit compute and professional workloads beyond gaming.

This group is a complete tie. Neither the Hellhound nor the Reaper holds any memory advantage whatsoever — buyers can disregard this category entirely as a differentiating factor and focus their decision on other specification groups.

Across the feature set that actually drives gaming and compute capability, these two cards are indistinguishable. Both support DirectX 12, ray tracing, and FSR4 — AMD's latest upscaling generation — along with AMD SAM (Smart Access Memory) for CPU-GPU bandwidth optimization, and up to 4 simultaneous displays. The absence of DLSS is expected on AMD hardware and is not a disadvantage relative to each other.

The only feature that separates the two is RGB lighting, which the Hellhound includes and the Reaper does not. This is purely an aesthetic consideration — it has zero impact on rendering performance, thermals, or compatibility. For builders assembling a themed system where visual cohesion matters, the Hellhound's RGB is a genuine perk. For those indifferent to lighting, it is simply irrelevant.

From a functional standpoint, this group is effectively a tie. The Hellhound gains a narrow aesthetic edge thanks to RGB lighting, but no capability that affects real-world performance or software compatibility differentiates these two cards here.

Display connectivity is identical across both cards: one HDMI 2.1b port and three DisplayPort outputs, for a total of four display connections — which aligns with the four-display limit noted in the features group. HDMI 2.1b is the current standard for high-bandwidth display output, capable of driving 4K at high refresh rates or 8K displays, making it well-suited for both gaming monitors and modern TVs.

Neither card offers USB-C, mini DisplayPort, or DVI outputs. The absence of USB-C is worth noting for users who rely on USB-C to DisplayPort cables or adapters for certain monitors, though the three full-size DisplayPort outputs largely offset this for multi-monitor setups. DVI's omission is entirely unremarkable given the port's obsolescence.

This group is a complete tie — port selection is identical in every respect, and neither the Hellhound nor the Reaper offers any connectivity advantage over the other.

Beneath the surface, these two cards are built on exactly the same foundation: the RDNA 4.0 architecture on a 5nm process node, with an identical 220W TDP and PCIe 5.0 interface. Same transistor count, same power envelope, same platform requirements. For system builders, this means power supply and motherboard compatibility decisions are interchangeable between the two.

The meaningful distinction in this group is physical size. The Hellhound measures 340 × 142 mm, while the Reaper comes in notably more compact at 304 × 127 mm — a difference of 36mm in length and 15mm in height. That gap is significant in practice: the Reaper will fit comfortably in mid-tower and smaller cases where the Hellhound may be a tight squeeze or outright incompatible. For small form factor or ITX builds especially, those extra centimeters can be the deciding factor.

The Reaper holds a clear advantage in this group for anyone working with space constraints, offering the same TDP and architecture in a meaningfully smaller footprint. The Hellhound's larger dimensions carry no listed benefit from the provided data — making the Reaper the more versatile choice from a physical compatibility standpoint.
