AMD FirePro M6100 vs AMD Radeon RX 7700 Comparison

The AMD Radeon RX 7700 and the AMD FirePro M6100 sit at opposite ends of the database: one is an active desktop graphics card from the Radeon RX 7000 series, the other an end-of-life mobile workstation module from the FirePro Mobile Mx100 generation. The recorded data shows a gulf between them so wide that they are not really competitors, but the comparison is instructive because it illustrates how far AMD's GPU architecture has travelled between GCN 2.0 and RDNA 3.0. On the single directly comparable benchmark in the database, the Geekbench OpenCL test, the RX 7700 scores 106028 against the FirePro M6100's 13354, a delta of 694 percent in the desktop card's favour. Every other metric in the recorded data points the same direction.

The Verdict

There is no scenario in the database where the FirePro M6100 comes out ahead. The RX 7700 wins the only head-to-head benchmark by 694 percent, sits in the 58th percentile against all GPUs versus the M6100's 54th, and posts an average benchmark score of 15852 against 13354. Buyers choosing between these two are effectively choosing between eras, not between trade-offs.

The RX 7700 is the pick for anyone running modern workloads. It supports DirectX 12 Ultimate (12_2), Vulkan 1.4, OpenGL 4.6, and includes 40 ray tracing cores, none of which the M6100 offers. Its 16 GB of GDDR6 on a 256-bit bus delivers 624.1 GB/s of bandwidth, while the FirePro's 2 GB of GDDR5 on a 128-bit bus manages 96.00 GB/s. The M6100's only defensible use case today is legacy mobile workstation hardware that still relies on the MXM-B (3.0) form factor, where it slots into machines whose display outputs are, as the data notes, portable-device dependent. Its production status is end-of-life; the RX 7700 is active.

Users who need current drivers, current API support, and modern compute throughput have one option here. Users maintaining an older mobile workstation chassis have the other.

Architecture Differences

The two GPUs represent different design philosophies separated by several process generations. The RX 7700 is built on the Navi 32 chip, codenamed Wheat Nas, using RDNA 3.0 architecture on TSMC's 5 nm process node. The FirePro M6100 uses the Emerald chip with GCN 2.0 architecture on TSMC's 28 nm node. Both parts share TSMC as a foundry, which is where the similarities end.

The transistor counts tell the story most starkly. The RX 7700 packs 28,100 million transistors onto a 346 mm² die, a density of 81.2M per mm². The M6100 carries 2,080 million transistors on a 160 mm² die at 13.0M per mm². That is roughly an order of magnitude more transistors on a die just over twice the area, a direct consequence of the node shrink and the architectural expansion it enabled.

The shader resources scale accordingly. The RX 7700 fields 2560 shading units, 160 texture mapping units, and 96 render output units. The M6100 has 896 shading units, 56 TMUs, and 16 ROPs. The desktop card also includes 40 dedicated ray tracing cores; the FirePro has none, and neither GPU lists tensor cores.

Raw throughput figures confirm the gap. The RX 7700 produces a pixel rate of 236.1 GPixel/s and a texture rate of 393.4 GTexel/s, against 17.60 GPixel/s and 61.60 GTexel/s for the M6100. FP32 compute lands at 25.18 TFLOPS for the RX 7700, which also matches that figure at FP16 with a 1:1 rate, while the FirePro delivers 1.971 TFLOPS FP32 and lists no FP16 figure at all.

Clock behaviour differs in kind as well as degree. The RX 7700 records a 1900 MHz base clock, a 2041 MHz game clock, and a 2459 MHz boost, with memory clocked at 2438 MHz for 19.5 Gbps effective. The M6100's database entry lists no base, boost, or game clock at all, only a 1500 MHz memory clock running at 6 Gbps effective. The mobile part simply was not documented with the same operational clock points.

Head-to-Head Benchmarks

Only one test appears in both GPUs' recorded results: the Geekbench OpenCL compute benchmark. The RX 7700 scores 106028; the FirePro M6100 scores 13354. That is a 694 percent advantage for the desktop card, and the database credits the RX 7700 with one win and the M6100 with zero in the head-to-head tally.

Context from each card's rival set sharpens the picture. The RX 7700's average benchmark score of 15852 places it within a tight cluster: essentially level with the AMD Radeon R9 370X (average score 15862, a delta of just 0.1 percent), slightly behind the AMD Radeon RX 9060 (16014, 1 percent back) and the NVIDIA GeForce RTX 3060 Ti (16129, 1.7 percent back), and just ahead of the AMD Radeon Pro W5500 (15679, a 1.1 percent lead). In other words, the RX 7700 trades blows with mainstream desktop parts from its performance neighbourhood.

The M6100's average of 13354 is likewise surrounded by peers, but they are mobile and low-tier workstation parts: the AMD Radeon RX 5500M sits dead level with a delta of 0 percent, the AMD Radeon HD 8950M is 0.2 percent ahead, the AMD Radeon Pro 555X is 0.3 percent behind, and the AMD Radeon Pro 555 is 0.4 percent ahead. Its percentile against all GPUs in the database is 54, against 58 for the RX 7700, though the percentile gap understates the practical difference that the head-to-head compute result exposes.

The RX 7700's other recorded results round out its profile. It scores 2865 in the 3DMark Steel Nomad DirectX 12 test, 20974 in PassMark G3D, 10963 in PassMark GPU Compute, and 1206 in PassMark G2D, with PassMark DirectX results of 261 (DX9), 92 (DX10), 186 (DX11), and 96 (DX12). The M6100 has no entries in any of these tests, consistent with its age and end-of-life status. The database simply has no direct gaming measurements for it beyond the single OpenCL result.

Specification Differences

Memory is the sharpest dividing line. The RX 7700 carries 16 GB of GDDR6 across a 256-bit bus for 624.1 GB/s of bandwidth. The M6100 carries 2 GB of GDDR5 across a 128-bit bus for 96.00 GB/s. For any workload that fits in 2 GB, the comparison holds; for anything larger, the FirePro cannot participate at all.

Form factor and power delivery diverge completely. The RX 7700 is a dual-slot desktop card measuring 267 mm long, 135 mm high, and 50 mm wide, connecting over PCIe 4.0 x16, drawing power through two 8-pin connectors, carrying a 200 W TDP, and requiring a suggested 550 W power supply. The M6100 is an MXM module with no external power connectors, no listed TDP, no suggested PSU, and no recorded dimensions, communicating over the MXM-B (3.0) interface. These parts are physically incompatible with each other's host systems.

Display connectivity reflects the same split. The RX 7700 offers one HDMI 2.1a output, two DisplayPort 2.1 outputs, and one USB Type-C. The M6100's outputs are listed as portable-device dependent, meaning they depended entirely on the laptop or workstation chassis hosting the module.

API support differs in tier. Both expose OpenGL 4.6, but the RX 7700 reaches DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the M6100 stops at DirectX 12 (12_0) and Vulkan 1.2.170. Release dates frame the gap: the M6100 arrived on 2014-05-26 and is now end-of-life, succeeded by Radeon Pro Mobile, while the RX 7700 launched on 2025-09-17, remains in active production, and follows the Navi II generation with Navi IV as successor. Neither card has a recorded launch MSRP.
