AMD FirePro W7000 vs AMD Radeon RX 6650 XT Comparison

The AMD FirePro W7000 and AMD Radeon RX 6650 XT are separated by a decade of GPU architecture evolution, and the benchmark data reflects that chasm clearly. The FirePro W7000, a GCN 1.0 part from the professional Wx000 line, relies on a 28 nm process and a 2,800 million-transistor Pitcairn chip. The RX 6650 XT, built on RDNA 2.0, uses a 7 nm process and packs 11,060 million transistors into a 237 mm² die. That process shrink yields a transistor density of 46.7M per mm² versus 13.2M for the older card. The architectural gap shows in raw compute: the RX 6650 XT delivers 10.79 TFLOPS FP32, while the FirePro W7000 manages 2.432 TFLOPS. The newer card also adds 32 ray-tracing cores, a feature entirely absent from the GCN part.

FAQ

Q: Which card has more shading units and texture units?

A: The AMD Radeon RX 6650 XT has 2048 shading units and 128 texture mapping units (TMUs), compared to the FirePro W7000’s 1280 shading units and 80 TMUs. The RX 6650 XT also doubles the render output units (ROPs) at 64 versus 32.

Q: How do their memory subsystems compare?

A: The FirePro W7000 uses 4 GB of GDDR5 on a 256-bit bus, delivering 153.6 GB/s bandwidth. The RX 6650 XT uses 8 GB of GDDR6 on a 128-bit bus, achieving 280.3 GB/s. Despite the narrower bus, the newer card’s faster memory (17.5 Gbps effective versus 4.8 Gbps) provides significantly higher bandwidth.

Q: What are the API support differences?

A: The RX 6650 XT supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the FirePro W7000 is limited to DirectX 12 (11_1) and Vulkan 1.2.170. Both cards support OpenGL 4.6.

Q: Which card has a higher pixel fill rate?

A: The RX 6650 XT has a pixel rate of 168.6 GPixel/s, which is over five times higher than the FirePro W7000’s 30.40 GPixel/s. Its texture rate is similarly dominant at 337.3 GTexel/s versus 76.00 GTexel/s.

Q: Are these cards the same physical size?

A: No. The FirePro W7000 is a single-slot card measuring 242 mm in length and 111 mm in height. The RX 6650 XT is a dual-slot design, though its dimensions are not listed in the data.

Q: How do their power requirements differ?

A: The FirePro W7000 has a 150 W TDP and requires a single 6-pin power connector. The RX 6650 XT has a 176 W TDP and uses a single 8-pin connector. Both cards have a suggested PSU rating of 450 W.

Head-to-Head Benchmarks

The head-to-head benchmark data presents a fascinating split: each card wins one of the two shared tests, and the margins are enormous in both directions. In the Geekbench OpenCL test, the FirePro W7000 scores 17808 against the RX 6650 XT’s 10111, a 76.1% advantage for the older card. This is a counterintuitive result given the massive compute advantage of the newer GPU, but it highlights the maturity of the FirePro’s driver stack for OpenCL workloads. The data shows the FirePro W7000’s average benchmark score is 19905, placing it at the 65th percentile of all GPUs, while the RX 6650 XT’s average is 19765, also at the 65th percentile. The delta between them in the overall average is just 0.7%, with the FirePro edging ahead.

The Vulkan test flips the script entirely. The RX 6650 XT scores 81306, while the FirePro W7000 manages only 22001. That is a 72.9% advantage for the newer card, demonstrating the RDNA 2 architecture’s vastly superior modern API performance. The RX 6650 XT’s Vulkan score is nearly four times that of the FirePro, and this is where the architectural gap becomes undeniable. The FirePro’s GCN 1.0 design was never optimized for Vulkan’s low-overhead model, and the numbers reflect that. In direct comparison, the RX 6650 XT also shows its strength in other benchmarks not shared with the FirePro: it scores 17166 in Passmark G3D, 7532 in Passmark GPU Compute, and 97969 in Geekbench Metal. The FirePro has no corresponding scores in those tests to compare against, but the RX 6650 XT’s raw numbers are substantial.

Specification Differences

The two cards differ across nearly every measurable specification. The FirePro W7000 uses a 28 nm Pitcairn chip from GCN 1.0, while the RX 6650 XT uses a 7 nm Navi 23 from RDNA 2.0. Transistor count jumps from 2,800 million to 11,060 million, and die size increases slightly from 212 mm² to 237 mm². The FirePro has no base or boost clock listed, while the RX 6650 XT runs at 2055 MHz base, 2410 MHz game, and 2635 MHz boost. Memory clocks differ dramatically: 1200 MHz (4.8 Gbps effective) on the FirePro versus 2190 MHz (17.5 Gbps effective) on the RX 6650 XT. Memory capacity doubles from 4 GB to 8 GB, and the bus width halves from 256-bit to 128-bit, yet bandwidth increases from 153.6 GB/s to 280.3 GB/s.

The RX 6650 XT has 2048 shading units, 128 TMUs, 64 ROPs, and 32 ray-tracing cores. The FirePro W7000 has 1280 shading units, 80 TMUs, and 32 ROPs, with no ray-tracing cores. Pixel rate jumps from 30.40 GPixel/s to 168.6 GPixel/s, and texture rate from 76.00 GTexel/s to 337.3 GTexel/s. FP32 compute goes from 2.432 TFLOPS to 10.79 TFLOPS, and the RX 6650 XT adds FP16 support at 21.59 TFLOPS (2:1), which the FirePro lacks entirely. The FirePro is single-slot with a 150 W TDP and 1x 6-pin power, while the RX 6650 XT is dual-slot with a 176 W TDP and 1x 8-pin power. The FirePro uses PCIe 3.0 x16 and outputs 4x DisplayPort 1.2; the RX 6650 XT uses PCIe 4.0 x8 and outputs 1x HDMI 2.1 plus 3x DisplayPort 1.4a. Both are end-of-life, but the FirePro launched in 2012 and the RX 6650 XT in 2022.

The Verdict

The data paints a clear picture: these are two different tools for two different jobs. The FirePro W7000 holds a 76.1% lead in Geekbench OpenCL, a test that likely reflects its professional-grade compute drivers and GCN 1.0’s strengths in certain compute workloads. Its average benchmark score of 19905 is marginally higher than the RX 6650 XT’s 19765, and it sits 0.1% above the NVIDIA Tesla K40m in the rival list. However, the RX 6650 XT crushes the FirePro in Vulkan by 72.9%, and its raw hardware specs are superior across the board: 4.4 times the FP32 compute, 5.5 times the pixel rate, and nearly double the memory bandwidth.

The RX 6650 XT’s nearest rival list shows it within 0.8% of the NVIDIA Quadro K5200 and 0.7% of the AMD FirePro D300, confirming it sits in the same performance tier as the FirePro W7000 overall. But the distribution of that performance is completely different. The FirePro wins the compute-focused OpenCL test decisively, while the RX 6650 XT wins the modern-graphics Vulkan test decisively. If your workload is legacy OpenCL compute, the FirePro is the better choice despite being a decade older. If your workload involves Vulkan, modern gaming, or any ray-traced content, the RX 6650 XT is the only rational option.

Where Each One Wins

The FirePro W7000 wins in OpenCL compute tasks. Its 76.1% lead in Geekbench OpenCL over the RX 6650 XT is the single largest margin in the head-to-head data. This suggests that for professional applications that still rely on OpenCL acceleration—think older CAD, simulation, or scientific compute packages—the FirePro’s mature GCN 1.0 drivers and 4 GB of GDDR5 on a 256-bit bus remain effective. Its single-slot design and 150 W TDP also make it easier to fit into dense workstation builds where space and cooling are constrained. The FirePro also edges the RX 6650 XT in overall average benchmark score (19905 versus 19765) and sits 0.7% ahead in that aggregate metric.

The RX 6650 XT wins in every modern rendering scenario. Its 72.9% Vulkan advantage demonstrates that it is the only one of the two that can handle current graphics APIs efficiently. Its 32 ray-tracing cores, 10.79 TFLOPS FP32, and 168.6 GPixel/s pixel rate make it suitable for gaming and real-time rendering, while the FirePro cannot compete in those areas. The RX 6650 XT also has 8 GB of memory versus 4 GB, and its memory bandwidth of 280.3 GB/s is nearly double. For DirectX 12 Ultimate workloads, the RX 6650 XT’s support for 12_2 is a hard requirement, whereas the FirePro’s 11_1 support is outdated. If you need HDMI 2.1 or DisplayPort 1.4a outputs, the RX 6650 XT provides those, while the FirePro only offers DisplayPort 1.2. In short, the FirePro wins legacy compute, and the RX 6650 XT wins everything else.
