AMD FirePro S7150 vs AMD Radeon RX 6600 XT Comparison

Where Each One Wins

The recorded benchmark data splits cleanly between these two AMD cards, with the AMD Radeon RX 6600 XT taking every head-to-head comparison in the database. The AMD FirePro S7150 holds no wins in the shared tests, while the RX 6600 XT wins both. That said, the FirePro S7150 is not without merit: it occupies the 73rd percentile among all GPUs, placing it slightly above the RX 6600 XT's 70th percentile in overall standing. The FirePro S7150 also posts a higher average benchmark score of 28,117 compared to the RX 6600 XT's 24,442, though that average includes a broader set of tests for the newer card.

The use-case split becomes clearer when examining the nature of the tests. The FirePro S7150 was a server-oriented product with no display outputs, suggesting it targeted compute workloads rather than interactive graphics. Its two recorded benchmarks, Geekbench OpenCL and Geekbench Vulkan, measure raw compute and API performance. The RX 6600 XT, by contrast, is a consumer Radeon card with display outputs, and its benchmark suite spans DirectX 9 through 12, Metal, OpenCL, Vulkan, and Passmark's G2D and G3D tests. The RX 6600 XT therefore wins on breadth of testing, while the FirePro S7150 wins on aggregate positioning relative to the entire GPU landscape.

For workloads that stress OpenCL compute, the RX 6600 XT is dramatically ahead. For Vulkan-based tasks, the RX 6600 XT again dominates. The FirePro S7150's strength lies in its historical role as a compute-oriented server card, but the data does not show any test where it outperforms the RX 6600 XT. The nearest rivals for the FirePro S7150 include the NVIDIA GeForce GTX 980 Ti (0.3% ahead), AMD Radeon Pro W5500X (0.5% ahead), AMD Radeon RX 7800M (0.8% ahead), and AMD Radeon Pro Vega 20 (1% ahead), all clustered within a single percentage point. The RX 6600 XT's nearest rivals are similarly close: Intel Arc A350M is 0.8% behind, NVIDIA GeForce GTX 1630 is 0.7% behind, NVIDIA GeForce GTX 780 Ti is 0.8% behind, and NVIDIA GeForce RTX 2080 SUPER is 1.1% behind. Both cards sit in competitive neighborhoods, but the FirePro S7150's higher percentile suggests it edges out the RX 6600 XT in global rank despite losing the direct comparisons.

Head-to-Head Benchmarks

The database records two direct comparisons between these cards, and the AMD Radeon RX 6600 XT wins both by substantial margins. In Geekbench OpenCL, the RX 6600 XT scores 80,503 against the FirePro S7150's 26,543, a delta of 67% in favor of the newer card. This is not a marginal improvement; the RX 6600 XT more than triples the FirePro S7150's compute score. The gap reflects the architectural leap from GCN 3.0 to RDNA 2.0, combined with a process node shrink from 28 nm to 7 nm.

In Geekbench Vulkan, the RX 6600 XT scores 72,417 against the FirePro S7150's 29,690, a delta of 59%. Again, the RX 6600 XT more than doubles the FirePro S7150's score. Vulkan performance is relevant for modern game engines and compute workloads, and the data shows the RX 6600 XT holds a commanding lead. The FirePro S7150's Vulkan support is listed as version 1.2.170, while the RX 6600 XT supports Vulkan 1.4, which may contribute to the difference.

These two tests are the only shared benchmarks in the database, so the head-to-head picture is limited but unambiguous. The RX 6600 XT wins both, with no recorded wins for the FirePro S7150. The magnitude of the wins, 67% and 59%, indicates a generational performance gap rather than a close contest. The FirePro S7150's nearest rivals cluster within 0.3% to 1% of its average score, suggesting it is competitive with cards like the GTX 980 Ti and Radeon Pro W5500X, but the RX 6600 XT is in a different performance class in these specific tests.

Specification Differences

The two cards differ substantially across nearly every specification category. The AMD FirePro S7150 was released on 2016-01-31, while the AMD Radeon RX 6600 XT was released on 2021-07-29, a gap of over five years. The FirePro S7150 uses the Tonga chip with GCN 3.0 architecture, while the RX 6600 XT uses Navi 23 with RDNA 2.0 architecture. The process node shrinks from 28 nm to 7 nm, both fabricated by TSMC.

Transistor counts and die sizes differ markedly. The FirePro S7150 packs 5,000 million transistors on a 366 mm² die, yielding a density of 13.7M per mm². The RX 6600 XT packs 11,060 million transistors on a 237 mm² die, yielding a density of 46.7M per mm². The RX 6600 XT has more than double the transistor count on a smaller die, reflecting the density improvement from the node shrink.

Clocks and memory configurations diverge. The FirePro S7150 has no recorded base or boost clock, but its memory runs at 1250 MHz (5 Gbps effective). The RX 6600 XT has a base clock of 1968 MHz, a boost clock of 2589 MHz, a game clock of 2359 MHz, and memory at 2000 MHz (16 Gbps effective). Memory type changes from GDDR5 to GDDR6, bus width narrows from 256-bit to 128-bit, but bandwidth increases from 160.0 GB/s to 256.0 GB/s.

Compute resources differ in ROPs and feature set. Both have 2048 shading units and 128 TMUs, but the FirePro S7150 has 32 ROPs while the RX 6600 XT has 64 ROPs. The RX 6600 XT also has 32 ray tracing cores, which the FirePro S7150 lacks. Pixel rate jumps from 29.44 GPixel/s to 165.7 GPixel/s, texture rate from 117.8 GTexel/s to 331.4 GTexel/s, and FP32 from 3.768 TFLOPS to 10.60 TFLOPS. FP16 performance rises from 7.537 TFLOPS to 21.21 TFLOPS.

Physical and interface specs also differ. The FirePro S7150 is single-slot with a 6-pin connector, 241 mm long, 111 mm tall, with no display outputs and PCIe 3.0 x16. The RX 6600 XT is dual-slot with an 8-pin connector, 190 mm long, 110 mm tall, 40 mm wide, with 1x HDMI 2.1 and 3x DisplayPort 1.4a, on PCIe 4.0 x8. Both have a 150 W vs 160 W TDP and both recommend a 450 W power supply. The FirePro S7150 has a launch MSRP of 2,399 USD, while the RX 6600 XT has a launch MSRP of 379 USD.

Architecture Differences

The architectural gap between these two cards is foundational. The FirePro S7150 uses GCN 3.0, AMD's third-generation Graphics Core Next design, built on the Tonga chip at 28 nm. GCN 3.0 was designed for compute-heavy workloads, which aligns with the FirePro S7150's server positioning and lack of display outputs. The RX 6600 XT uses RDNA 2.0, a gaming-first architecture that also incorporates ray tracing hardware. RDNA 2.0 is built on the Navi 23 chip at 7 nm, and it represents a significant departure from GCN's compute-oriented design.

The process node difference is stark: 28 nm versus 7 nm, both at TSMC. This allows the RX 6600 XT to fit 11,060 million transistors into 237 mm², while the FirePro S7150 fits only 5,000 million into 366 mm². The transistor density more than triples, from 13.7M per mm² to 46.7M per mm². This density increase directly enables the higher clock speeds and compute rates of the RX 6600 XT.

Cache and feature differences are visible in the API support. The FirePro S7150 supports DirectX 12 (12_0), while the RX 6600 XT supports DirectX 12 Ultimate (12_2), which includes features like ray tracing and mesh shaders. The RX 6600 XT has 32 ray tracing cores, a hardware feature entirely absent from the FirePro S7150. Vulkan support also advances from version 1.2.170 to version 1.4.

The memory subsystem reflects architectural evolution. The FirePro S7150 uses GDDR5 on a 256-bit bus, while the RX 6600 XT uses GDDR6 on a 128-bit bus. The narrower bus is compensated by much higher effective memory speed (16 Gbps versus 5 Gbps), resulting in higher total bandwidth (256.0 GB/s versus 160.0 GB/s). This trade-off is typical of RDNA generations, which favor faster memory over wider buses.

Compute rates scale dramatically. FP32 throughput rises from 3.768 TFLOPS to 10.60 TFLOPS, a 2.8x increase. FP16 throughput rises from 7.537 TFLOPS to 21.21 TFLOPS, both using a 2:1 ratio. Pixel rate jumps from 29.44 GPixel/s to 165.7 GPixel/s, and texture rate from 117.8 GTexel/s to 331.4 GTexel/s. The RX 6600 XT also doubles the ROP count from 32 to 64, which contributes to the pixel rate increase.

The FirePro S7150's predecessor is FirePro Terascale, and its successor is Radeon Pro GCN. The RX 6600 XT's predecessor is Navi, and its successor is Navi III. Both cards are end-of-life in production status. The FirePro S7150 belongs to the FirePro Server (Sx100) generation, while the RX 6600 XT belongs to the Navi II (RX 6000) generation within the Radeon RX 6000 series.

The Verdict

The data points to a clear choice for most users: the AMD Radeon RX 6600 XT. It wins both head-to-head benchmarks by margins of 67% and 59%, offers modern API support including DirectX 12 Ultimate and Vulkan 1.4, and includes ray tracing hardware. Its display outputs make it usable for interactive graphics, while the FirePro S7150 has no outputs at all. The RX 6600 XT also has a lower launch MSRP of 379 USD compared to the FirePro S7150's 2,399 USD, though both cards are now end-of-life.

The FirePro S7150 retains a niche argument. Its 73rd percentile standing among all GPUs is higher than the RX 6600 XT's 70th percentile, and its average benchmark score of 28,117 exceeds the RX 6600 XT's 24,442. These figures suggest that in the broader GPU population, the FirePro S7150 holds its own against a wider range of competitors. Its nearest rivals include the GTX 980 Ti and Radeon Pro W5500X, all within 1% of its average score. For compute workloads that were optimized for GCN 3.0 and server deployments where display output is unnecessary, the FirePro S7150 could still be relevant, but the benchmark data does not show it beating the RX 6600 XT in any shared test.

The RX 6600 XT's nearest rivals include the GTX 1630, Arc A350M, GTX 780 Ti, and RTX 2080 SUPER, all within 1.1% of its average score. This places it in a competitive mid-range segment, despite its higher raw performance in the head-to-head tests. The RX 6600 XT's benchmark suite covers DirectX 9 through 12, Metal, OpenCL, Vulkan, and Passmark tests, giving a more complete picture of consumer workloads.

The verdict depends on the workload. For gaming, graphics, ray tracing, or any task requiring display output, the RX 6600 XT is the only viable choice based on the data. For server compute without display needs, the FirePro S7150's higher global percentile and average score suggest it may still compete with its contemporary peers, but it cannot match the RX 6600 XT's raw performance in OpenCL or Vulkan. The database records 0 wins for the FirePro S7150 and 2 wins for the RX 6600 XT in head-to-head testing, and that record is decisive.
