AMD FirePro D500 vs AMD Radeon 780M Comparison

Where Each One Wins

The benchmark data splits cleanly between these two AMD parts, and the winner is not who you might expect from a generational standpoint. The AMD Radeon 780M dominates the single head-to-head comparison available, taking the Geekbench Vulkan test with a score of 33683 against the FirePro D500's 18533. That is a 45% deficit for the older workstation card, a massive gap in raw API performance.

However, the FirePro D500 is not without its own territory. It holds a percentile rank of 62 against all GPUs, edging out the 780M's 61st percentile. Its average benchmark score of 18533 is also higher than the 780M's 17588 average across all tests. This suggests the FirePro D500 is more consistent in the specific workloads where it was designed to excel, even if its peak performance in a single modern API test falls short.

The 780M wins decisively in compute throughput per watt and in modern API feature support. Its 8.909 TFLOPS FP32 performance and 8.909 TFLOPS FP16 (1:1) rate are far beyond the FirePro D500's 2.227 TFLOPS FP32. The 780M also carries 12 ray tracing cores, something the older card lacks entirely. For any workload that leverages ray tracing or FP16 compute, the 780M is the only viable choice here.

The FirePro D500 wins on memory bandwidth and capacity, which historically matters for large frame buffers and multi-display setups. It has 3 GB of dedicated GDDR5 on a 384-bit bus, delivering 243.8 GB/s. The 780M uses system shared memory, making its bandwidth "System Dependent" — a wildcard that can be a strength or a weakness depending on the platform it is paired with.

Architecture Differences

This is a clash of two completely different GPU generations and design philosophies. The FirePro D500 is built on the Tahiti chip using GCN 1.0 architecture, manufactured on a 28 nm process at TSMC. That chip packs 4,313 million transistors into a 352 mm² die, yielding a transistor density of 12.3 million per square millimeter. The 780M uses the Phoenix chip with RDNA 3.0 architecture, also from TSMC but on a 4 nm process. It integrates 25,390 million transistors into a much smaller 178 mm² die, achieving 142.6 million transistors per square millimeter — over 11 times the density.

The compute configuration differs drastically. The FirePro D500 fields 1536 shading units, 96 texture mapping units, and 32 ROPs. The 780M has half the shading units at 768, but matches the ROP count at 32 and cuts TMUs to 48. Despite fewer shading units, the 780M achieves vastly higher clock speeds: a base of 800 MHz and boost of 2900 MHz, versus the FirePro D500's unspecified base and boost clocks (only memory clock is listed at 1270 MHz, 5.1 Gbps effective). This clock advantage, combined with architectural efficiency, explains the 780M's far higher pixel rate of 92.80 GPixel/s versus 23.20 GPixel/s, and texture rate of 139.2 GTexel/s versus 69.60 GTexel/s.

Memory architecture is a fundamental split. The FirePro D500 uses 3 GB of GDDR5 on a 384-bit interface, while the 780M relies entirely on system shared memory with no dedicated VRAM. The 780M's bandwidth is listed as "System Dependent," meaning its performance scales with the host system's memory speed and configuration. The FirePro D500's fixed 243.8 GB/s is a known quantity.

API support shows the generational gap clearly. The FirePro D500 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The 780M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 780M also adds 12 ray tracing cores, a feature completely absent from the FirePro D500. Power consumption tells the story of efficiency: the FirePro D500 is a 274 W dual-slot card requiring a 600 W PSU, while the 780M is an integrated graphics processor rated at just 15 W with no power connectors.

The Verdict

The data points to a clear split based on use case. For anyone building a modern system where size, power, and current API support matter, the AMD Radeon 780M is the obvious choice. Its 45% lead in the Vulkan benchmark over the FirePro D500 is not a marginal edge — it is a decisive generational leap. The 780M also offers ray tracing cores, FP16 compute at a 1:1 ratio, and DirectX 12 Ultimate support, none of which the FirePro D500 can match. Its 15 W power draw makes it suitable for compact systems where a 274 W dual-slot card would be impractical.

The FirePro D500 still has a niche. Its dedicated 3 GB GDDR5 frame buffer with 243.8 GB/s bandwidth is valuable for workloads that need consistent memory performance without relying on system RAM. Its 62nd percentile ranking against all GPUs, higher than the 780M's 61st, suggests it holds its own in legacy or workstation-specific tasks. The 6x mini-DisplayPort 1.2 and 1x SDI outputs are a professional feature set that the 780M cannot offer, as its display outputs are "Motherboard Dependent."

The 780M is the better all-rounder for modern gaming and compute. The FirePro D500 is a specialist tool for multi-display professional environments where its fixed memory and output configuration are advantages. The production statuses reinforce this: the FirePro D500 is end-of-life, while the 780M is active.

Q: What is the performance gap in the only head-to-head benchmark?

A: In Geekbench Vulkan, the Radeon 780M scores 33683 against the FirePro D500's 18533, a 45% advantage for the 780M.

Q: Which GPU has better API support?

A: The Radeon 780M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the FirePro D500 supports DirectX 12 (11_1) and Vulkan 1.2.170. Both support OpenGL 4.6.

Head-to-Head Benchmarks

The single available head-to-head test is Geekbench Vulkan, and it is a decisive victory for the Radeon 780M. The 780M posts a score of 33683, while the FirePro D500 manages 18533. The delta percentage is -45%, meaning the FirePro D500 scores 45% lower than the 780M. This is not a close contest by any measure.

To contextualize this, look at the nearest rivals for each card. The FirePro D500's 18533 score sits between the AMD Radeon RX 560X (18626, 0.5% higher) and the Intel Arc A770M (18383, 0.8% lower). It is also within a point of the AMD Radeon RX 460 (18373, 0.9% lower). This places the FirePro D500 firmly in mid-range territory for Vulkan performance, roughly equivalent to entry-level discrete cards from several generations ago.

The Radeon 780M's 33683 score, by contrast, is nearly double that of its nearest rivals. Its closest listed competitor is the NVIDIA GeForce RTX 4060 at 17639, which the 780M beats by a staggering margin. The AMD Radeon Pro 560 (17551) and AMD Radeon HD 7790 (17666) are similarly far behind. This indicates the 780M's Vulkan performance is in a completely different class, likely due to its high boost clock of 2900 MHz and RDNA 3.0 architecture.

The 780M's other benchmark scores reinforce its strength. It posts 18602 in Geekbench OpenCL, which is consistent with its Vulkan showing. Its 3DMark Steel Nomad DX12 score of 480 is a separate data point, but the Vulkan and OpenCL results together paint a picture of a GPU that punches well above its integrated status.
