Galax GeForce RTX 5080 1-Click OC VS Sapphire Radeon AI Pro R9700

These two GPUs tell a fascinating architectural story. The Galax RTX 5080 launches from a significantly higher base clock (2295 MHz vs. 1660 MHz), meaning it delivers sustained performance well before any boost algorithm kicks in — a real advantage in workloads that don't push the GPU to its thermal ceiling. The Sapphire R9700, however, closes the gap considerably at peak, reaching a 2920 MHz turbo versus the RTX 5080's 2625 MHz, suggesting its architecture is tuned to burst aggressively when thermals allow.

Where the RTX 5080 pulls decisively ahead is in raw compute throughput: its 56.45 TFLOPS of floating-point performance and 882 GTexels/s texture rate — backed by 10,752 shading units — reflect a much wider execution engine. The R9700's 4,096 shading units and 47.8 TFLOPS indicate a narrower but higher-clocked design. In shader-heavy tasks like ray tracing, AI-accelerated rendering, or modern rasterization, the RTX 5080's sheer unit count gives it a structural edge. Conversely, the R9700 counters with a faster memory subsystem (2518 MHz vs. 1875 MHz) and a higher pixel fill rate (373.8 GPixel/s vs. 294 GPixel/s), thanks to its higher ROP count (128 vs. 112), which benefits high-resolution output and bandwidth-bound scenarios.

Overall, the Galax RTX 5080 holds a clear advantage in compute and texture throughput — the specs most relevant to general gaming and GPU compute workloads. The Sapphire R9700 carves out a niche edge in pixel output rate and memory bandwidth efficiency, which may matter in specific high-resolution or fill-rate-limited use cases. Both cards support double-precision floating point, making them relevant for mixed professional workloads, but the RTX 5080's broader execution resources make it the stronger all-round performer based on these specs alone.

The Galax GeForce RTX 5080 1-Click OC features an effective memory speed of 30000 MHz, which is significantly faster than the Sapphire Radeon AI Pro R9700’s 20100 MHz. The RTX 5080 also boasts a higher maximum memory bandwidth of 960 GB/s, compared to the R9700’s 644.6 GB/s. In terms of VRAM, the R9700 has a much larger capacity at 32GB, while the RTX 5080 is equipped with 16GB of VRAM.

Both products utilize a 256-bit memory bus width and support Error-Correcting Code (ECC) memory, ensuring reliable data handling and stability during intensive tasks. The RTX 5080 uses the newer GDDR7 memory type, while the R9700 is equipped with GDDR6 memory, which is a previous generation but still provides strong performance.

While both cards provide high-performance memory features, the RTX 5080 leads in memory speed and bandwidth, while the R9700 excels in VRAM capacity.

Both the Galax GeForce RTX 5080 1-Click OC and the Sapphire Radeon AI Pro R9700 support DirectX 12 Ultimate, OpenGL 4.6, and ray tracing, with both also being capable of handling 3D graphics. The RTX 5080 supports OpenCL 3, while the R9700 is limited to OpenCL 2.2. Both cards support multi-display technology and can drive up to 4 supported displays.

In terms of advanced features, the RTX 5080 uses Intel Resizable BAR, while the R9700 supports AMD SAM. Neither card supports XeSS (XMX), and both are free from LHR (Lite Hash Rate) limitations. The RTX 5080 has RGB lighting, whereas the R9700 does not.

Overall, both products share many core features, but the RTX 5080 has slight advantages in OpenCL version and additional aesthetics with RGB lighting.

The Galax GeForce RTX 5080 1-Click OC includes one HDMI output and three DisplayPort outputs, offering versatile display connectivity. In contrast, the Sapphire Radeon AI Pro R9700 lacks an HDMI output but provides four DisplayPort outputs. Neither card features USB-C ports, DVI outputs, or mini DisplayPort outputs.

While both cards support DisplayPort outputs, the RTX 5080 has one HDMI output, which the R9700 does not. The R9700, however, provides an additional DisplayPort output, bringing the total to four.

In terms of ports, the RTX 5080 offers slightly more flexibility for users who prefer HDMI connections, while the R9700 leans more toward DisplayPort-heavy setups.

The Galax GeForce RTX 5080 1-Click OC uses the Blackwell GPU architecture, while the Sapphire Radeon AI Pro R9700 is built on the RDNA 4.0 architecture. The RTX 5080 has a Thermal Design Power (TDP) of 360W, higher than the R9700’s 300W TDP. Both cards support PCI Express (PCIe) version 5, ensuring fast data transfer speeds. The RTX 5080 has a 5 nm semiconductor size, while the R9700 uses a slightly smaller 4 nm semiconductor.

In terms of transistor count, the R9700 has more at 53900 million, compared to the RTX 5080’s 45600 million. Both cards lack air-water cooling systems, which may influence cooling setups. The RTX 5080 is larger in size, measuring 315 mm in width and 140.5 mm in height, while the R9700 is more compact, with a width of 266.7 mm and a height of 111 mm.

Overall, the RTX 5080 is larger and has a higher TDP, while the R9700 is built on a more advanced semiconductor process with a higher transistor count and a smaller form factor.
