AMD FirePro W4300 vs AMD Radeon HD 7770M Comparison

The Verdict

The data shows two very different AMD workstation and mobile graphics solutions separated by more than just their release dates. The AMD Radeon HD 7770M, a mobile part from the London generation, holds a higher percentile ranking at 54% versus the FirePro W4300's 50%, but this ranking is based on different benchmark suites. The HD 7770M scores 13,536 in Geekbench Metal, while the FirePro W4300 scores 11,225 in Geekbench OpenCL. These are not directly comparable tests, so the percentile difference primarily reflects the position within each card's respective test pool rather than a head-to-head performance verdict.

For users choosing between these two end-of-life products, the decision hinges on workload type and platform. The FirePro W4300 is the clear choice for compute-heavy professional tasks, offering nearly double the FP32 throughput at 1,428.5 GFLOPS versus 691.2 GFLOPS, along with quadruple the memory capacity at 4 GB versus 1 GB. The HD 7770M, with its lower 32 W TDP and portable-device-dependent display outputs, belongs in notebooks where power efficiency and basic acceleration matter more than raw compute. The benchmark data shows the W4300 is positioned for desktop workstations with four mini-DisplayPort outputs and a PCIe 3.0 x16 interface, while the HD 7770M is a mobile solution with no fixed display configuration.

Architecture Differences

The architectural gap between these two GPUs spans one full GCN generation. The HD 7770M uses the Chelsea chip built on GCN 1.0, while the FirePro W4300 employs the Bonaire chip on GCN 2.0. Both are fabricated on the same 28 nm process at TSMC, but the transistor counts tell the story of their different roles. The FirePro W4300 packs 2,080 million transistors across a 160 mm² die, yielding a transistor density of 13.0M per mm². The HD 7770M contains 1,500 million transistors on a smaller 123 mm² die, with a density of 12.2M per mm².

The shader configuration differs substantially. The FirePro W4300 carries 768 shading units and 48 texture mapping units, while the HD 7770M has 512 shading units and 32 TMUs. Both share 16 ROPs, meaning pixel output capability per clock is identical in structure, but the W4300's higher clock-derived rates push it ahead. The memory subsystem also diverges: the W4300 runs its GDDR5 at 1500 MHz with 6 Gbps effective throughput, while the HD 7770M's GDDR5 operates at 1000 MHz with 4 Gbps effective. Both use a 128-bit bus, but the W4300's faster memory yields 96.00 GB/s of bandwidth versus 64.00 GB/s.

API support shows another generational step. The FirePro W4300 supports DirectX 12 (12_0), while the HD 7770M is limited to DirectX 12 (11_1). OpenGL 4.6 and Vulkan 1.2.170 are common to both. The W4300's PCIe 3.0 x16 interface doubles the bus bandwidth potential of the HD 7770M's PCIe 2.0 x16 connection, which matters for professional workloads that stream data between system memory and the GPU.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two cards, so the comparison rests on their individual recorded scores and architectural specifications. The HD 7770M posts a Geekbench Metal score of 13,536, placing it at the 54th percentile of all GPUs in the database. Its nearest rivals include the AMD Radeon RX 9070 XT at 13,543 (a mere 0.1% higher), the NVIDIA GeForce GTX 570 at 13,515 (0.2% lower), the NVIDIA P106-090 at 13,470 (0.5% lower), and the AMD Radeon Pro 555 at 13,407 (1% lower). This clustering shows the HD 7770M sits in a tight performance band where a single percent separates it from four other cards.

The FirePro W4300 records a Geekbench OpenCL score of 11,225, at the 50th percentile. Its nearest rivals are the AMD Radeon Pro WX 3200 at 11,228 (statistically tied at 0% delta), the NVIDIA GeForce GTX 780M at 11,261 (0.3% higher), and two NVIDIA RTX PRO 6000 variants, both at 11,088 (1.2% lower). The W4300's position here shows it is essentially equivalent to the WX 3200 in OpenCL compute, while slightly outpacing the RTX PRO 6000 Blackwell Max-Q cards in this specific test.

In raw specification terms, the FirePro W4300 dominates the compute metrics. Its FP32 output of 1,428.5 GFLOPS is more than double the HD 7770M's 691.2 GFLOPS, a 106.7% advantage. Texture fill rate follows the same pattern: 44.64 GTexel/s versus 21.60 GTexel/s, a 106.7% lead. Pixel rate increases by a smaller margin, 14.88 GPixel/s versus 10.80 GPixel/s, a 37.8% improvement. Memory bandwidth jumps from 64.00 GB/s to 96.00 GB/s, a 50% gain.

Specification Differences

The two cards diverge across nearly every measurable specification. The FirePro W4300 ships with 4 GB of GDDR5 memory, while the HD 7770M has only 1 GB. Both use a 128-bit memory bus, but the W4300's memory clock of 1500 MHz (6 Gbps effective) exceeds the HD 7770M's 1000 MHz (4 Gbps effective). This produces 96.00 GB/s of bandwidth on the W4300 versus 64.00 GB/s on the HD 7770M.

Shader resources favor the W4300: 768 shading units and 48 TMUs versus 512 shading units and 32 TMUs. Both maintain 16 ROPs. The pixel rate is 14.88 GPixel/s on the W4300 and 10.80 GPixel/s on the HD 7770M. Texture rate reaches 44.64 GTexel/s on the W4300 and 21.60 GTexel/s on the HD 7770M. FP32 compute is 1,428.5 GFLOPS on the W4300 and 691.2 GFLOPS on the HD 7770M.

Power and physical characteristics differ dramatically. The FirePro W4300 has a 50 W TDP, a single-slot form factor, no power connectors, a suggested PSU of 250 W, and measures 171 mm in length and 69 mm in height. The HD 7770M draws only 32 W, has no fixed slot width, and its display outputs are portable device dependent. The W4300 offers four mini-DisplayPort 1.2 outputs. The bus interface is PCIe 3.0 x16 on the W4300 versus PCIe 2.0 x16 on the HD 7770M.

DirectX support differs as noted: 12 (12_0) on the W4300 versus 12 (11_1) on the HD 7770M. The transistor counts are 2,080 million versus 1,500 million, with die sizes of 160 mm² versus 123 mm². Release dates are separated by over three years: the HD 7770M launched in April 2012, and the FirePro W4300 in November 2015.

Where Each One Wins

The FirePro W4300 wins in every raw compute and memory metric recorded. Its FP32 performance is 106.7% higher, texture fill rate is 106.7% higher, and pixel rate is 37.8% higher. The memory bandwidth advantage is 50%, and the 4 GB frame buffer is four times larger, which matters for professional applications that hold large datasets or high-resolution textures. The W4300's four mini-DisplayPort 1.2 outputs and PCIe 3.0 x16 interface make it a workstation card designed for multi-monitor setups and data-intensive workflows. Its DirectX 12 (12_0) support provides a more modern feature level for applications that use the latest API features.

The HD 7770M wins in power efficiency and portability. Its 32 W TDP is 36% lower than the W4300's 50 W TDP, making it suitable for notebooks where thermal and power budgets are constrained. The portable-device-dependent display outputs indicate this is a mobile GPU, not a desktop card. Its Geekbench Metal score of 13,536 at the 54th percentile shows strong performance in Apple's Metal API environment, and its nearest rival cluster (RX 9070 XT at 0.1% higher, GTX 570 at 0.2% lower) suggests it holds its own in that specific test. The HD 7770M's lower transistor count and smaller die also point to a more modest manufacturing footprint.

For use-case decisions, the data points to the FirePro W4300 for anyone needing compute density, larger memory capacity, or professional display connectivity in a desktop workstation. The HD 7770M is the only choice for mobile platforms, and its lower power draw plus competitive Metal benchmark score make it a reasonable option for portable devices that prioritize battery life over peak throughput. The W4300's OpenCL score of 11,225 at the 50th percentile, statistically tied with the Radeon Pro WX 3200, confirms its position as a mid-tier professional compute card. The HD 7770M's Metal score, ranking above 54% of all GPUs, indicates it punches above its weight in that specific API.

Neither card offers ray tracing or tensor cores, and both are end-of-life products. The architectural gap from GCN 1.0 to GCN 2.0 brings a transistor density increase from 12.2M per mm² to 13.0M per mm², but the practical differences come from the W4300's larger chip, higher clocks, and doubled memory. The HD 7770M's closest rival in the database, the RX 9070 XT, sits a mere 0.1% higher in score, while the W4300's closest rival, the WX 3200, is exactly tied. These positions suggest both cards are well-matched against their immediate peers, just in different performance tiers and test environments.
