Architecture Differences

The AMD FirePro M6100 is built on GCN 2.0 architecture, using the Emerald chip, and belongs to the FirePro Mobile (Mx100) generation. The NVIDIA GeForce GTX 780M uses the Kepler architecture with the GK104 chip, part of the GeForce 700M generation. Both GPUs are manufactured on a 28 nm process at TSMC, but their transistor densities differ slightly: the AMD chip achieves 13.0M transistors per mm², while the NVIDIA chip reaches 12.0M per mm².

The NVIDIA GPU packs substantially more silicon. It contains 3,540 million transistors on a 294 mm² die, compared to the AMD’s 2,080 million transistors on a 160 mm² die. That larger silicon budget translates into a wider execution engine: the GTX 780M has 1,536 shading units, 128 texture mapping units, and 32 ROPs. The FirePro M6100 counters with 896 shading units, 56 TMUs, and 16 ROPs.

Clock behavior also separates the two. The NVIDIA part has defined base and boost clocks of 771 MHz and 797 MHz, respectively. The AMD part lists no base or boost clock in the database, only a memory clock of 1500 MHz (6 Gbps effective). The GTX 780M’s memory runs at 1250 MHz with 5 Gbps effective transfer.

API support shows a notable split. Both support DirectX 12, but the FirePro M6100 reaches the 12_0 feature level, while the GTX 780M is capped at 11_0. OpenGL support is identical at 4.6. Vulkan support is close, with the AMD card at version 1.2.170 and the NVIDIA card at 1.2.175.

Both cards use MXM modules with an MXM-B (3.0) bus interface and no power connectors. Display outputs are portable device dependent for both. The AMD card has no TDP listed, while the NVIDIA card is rated at 122 W. The AMD FirePro M6100 was released later, on 2014-05-26, while the GTX 780M came earlier on 2013-05-10. Both are now end-of-life products.

Where Each One Wins

The AMD FirePro M6100 wins the only directly comparable benchmark in the database: Geekbench OpenCL. Its 13,354 score beats the GTX 780M’s 12,769 by 4.6%. This gives the AMD card a clear edge in general-purpose compute workloads that rely on OpenCL acceleration, where its GCN 2.0 architecture and higher effective memory clock (6 Gbps vs 5 Gbps) appear to help.

The NVIDIA GeForce GTX 780M, however, offers advantages that go beyond the single shared test. It has dedicated Metal and Vulkan scores, 8,319 and 12,696 respectively. These are not available for the AMD card, which means the NVIDIA GPU is the better choice for applications that use those specific APIs. The GTX 780M also carries 4 GB of VRAM on a 256-bit bus delivering 160.0 GB/s memory bandwidth, double the capacity and 66.7% more bandwidth compared to the FirePro M6100, making it the stronger option for scenarios with large textures or datasets.

The NVIDIA card’s higher pixel rate (25.50 GPixel/s versus 17.60 GPixel/s) and texture rate (102.0 GTexel/s versus 61.60 GTexel/s) point to stronger rasterization throughput. Its 122 W TDP rating suggests a higher power ceiling, which pairs with its larger die and higher clock limits. In benchmark ranking, the AMD card holds a 4-percentile advantage over the GTX 780M, 54th to the 50th.

Head-to-Head Benchmarks

The database records one direct head-to-head benchmark between these two GPUs: Geekbench OpenCL. The AMD FirePro M6100 wins with 13,354 points versus 12,769 points for the NVIDIA GeForce GTX 780M, a margin of 4.6%. That is a meaningful gap for a single compute API, putting the AMD card ahead in OpenCL workloads. The AMD part’s higher effective memory clock, 6 Gbps versus 5 Gbps, and its newer GCN 2.0 architecture likely contribute to this result.

The NVIDIA GeForce GTX 780M does not win the shared test, but it posts additional results that the AMD card cannot match. Its Vulkan score of 12,696 is close to its OpenCL score, indicating consistent performance across compute APIs. The Metal score of 8,319 is lower, but it still represents a usable result for Apple-oriented workloads. These extra scores give the GTX 780M a broader benchmark profile, even though its average score across all three tests, 11,261, drops below the AMD’s single-test average of 13,354.

Looking at the rivals around each card provides context. The FirePro M6100’s nearest rival is the AMD Radeon RX 5500M with an average score of 13,356, only 0.0% away. The AMD Radeon HD 8950M sits 0.2% behind, and the Radeon Pro 555X is 0.3% ahead. For the GTX 780M, the AMD Radeon Pro WX 3200 and AMD FirePro W4300 are both 0.3% ahead, while the NVIDIA RTX PRO 6000 Blackwell Max-Q and RTX PRO 6000D Blackwell Max-Q are 1.6% ahead. These comparisons show both cards sitting in similar performance tiers relative to their respective neighbors, despite the AMD card’s head-to-head win.

In summary, the AMD FirePro M6100 takes the only direct compute benchmark, while the NVIDIA GeForce GTX 780M offers higher raw throughput metrics, double the memory capacity, and support for additional APIs. The choice between them depends on whether the workload prioritizes OpenCL compute (favoring AMD) or memory capacity, rasterization rates, and API breadth (favoring NVIDIA).
