AMD FirePro W8000 vs AMD Radeon RX 6600 XT Comparison

AMD FirePro W8000 and AMD Radeon RX 6600 XT represent two very different eras of AMD graphics hardware. The FirePro W8000 is a workstation-oriented card from the GCN 1.0 generation, while the RX 6600 XT is a mainstream gaming card built on RDNA 2.0. The benchmark data shows a clear generational gap, with the RX 6600 XT dominating in every recorded test, but the FirePro W8000 still holds relevance in specific legacy workstation contexts.

Where Each One Wins

The RX 6600 XT wins every head-to-head benchmark recorded in the database. In OpenCL compute, it scores 80,503 against the FirePro W8000’s 24,440, a delta of -69.6% from the perspective of the older card. That is a massive lead, roughly 3.3 times the raw score. In Vulkan, the RX 6600 XT scores 72,417 versus 33,981, a delta of -53.1%, meaning it is more than twice as fast. There is no test in the database where the FirePro W8000 comes out ahead. Its wins are zero; the RX 6600 XT has two.

The FirePro W8000’s only practical advantage is its workstation heritage. With 4 GB of GDDR5 memory, a 256-bit bus, and 176.0 GB/s of bandwidth, it was built for professional visualization and compute tasks of its era. Its 1792 shading units, 112 TMUs, and 32 ROPs are respectable for 2012 hardware, but the architecture is ancient by modern standards. The RX 6600 XT, with 2048 shading units, 128 TMUs, and 64 ROPs, simply has more of everything, plus a 7 nm process node versus 28 nm. For any modern workload, the RX 6600 XT is the clear winner. The FirePro W8000 only makes sense if you specifically need its legacy DisplayPort 1.2 and SDI outputs for old professional equipment.

The Verdict

The data is unambiguous: pick the RX 6600 XT for nearly any task. Its OpenCL score of 80,503 is over three times the FirePro W8000’s 24,440, and its Vulkan score of 72,417 is more than double the 33,981. The RX 6600 XT also has 8 GB of GDDR6 memory versus 4 GB of GDDR5, and its 256.0 GB/s bandwidth exceeds the FirePro’s 176.0 GB/s. The newer card is smaller (190 mm versus 279 mm), uses less power (160 W versus 225 W), and requires only a single 8-pin power connector instead of two 6-pin connectors. Its PCIe 4.0 x8 interface is also newer than PCIe 3.0 x16.

The FirePro W8000 should only be chosen if you have a specific, legacy workstation requirement that demands its SDI output or its exact GCN 1.0 feature set. For gaming, general compute, or any modern rendering workload, the RX 6600 XT is the only rational choice. The percentile ranking supports this: the FirePro W8000 sits at the 75th percentile of all GPUs, while the RX 6600 XT sits at the 70th, but that is because the older card’s average benchmark score of 29,211 is inflated by its two recorded tests, whereas the RX 6600 XT’s average of 24,442 includes a wider range of workloads, including lower-end DirectX 9 and DirectX 10 tests.

Head-to-Head Benchmarks

The OpenCL test is the most striking. The RX 6600 XT scores 80,503, while the FirePro W8000 scores 24,440. That is a delta of -69.6%, meaning the FirePro delivers less than a third of the newer card’s performance. This is a compute-heavy workload, and the RDNA 2.0 architecture’s 10.60 TFLOPS FP32 throughput versus the GCN 1.0’s 3.226 TFLOPS explains the gap. The RX 6600 XT also supports FP16 at 21.21 TFLOPS (2:1), a feature the FirePro lacks entirely.

In Vulkan, the RX 6600 XT scores 72,417 against 33,981, a delta of -53.1%. Vulkan is a modern low-level API, and the FirePro’s support for version 1.2.170 is functional but not optimized for the same way as the RX 6600 XT’s 1.4 support. The newer card’s 32 ray accelerators also give it hardware-accelerated ray tracing, which the FirePro cannot do. The delta in this test is smaller than OpenCL, but still decisive. The RX 6600 XT is more than twice as fast.

These two tests are the only head-to-head comparisons in the database, and the RX 6600 XT wins both. The FirePro W8000’s nearest rivals in the database, such as the AMD Radeon RX Vega M GH (average score 29,197, delta 0%) and Intel Arc A370M (29,175, delta 0.1%), show it is competitive with other older or low-end parts, but none of them approach the RX 6600 XT. The RX 6600 XT’s nearest rivals include the NVIDIA GeForce GTX 1630 (24,277, delta 0.7%) and Intel Arc A350M (24,647, delta -0.8%), which are far closer in performance, but still behind.
