AMD FirePro W4190M vs NVIDIA GeForce GT 755M Comparison

Head-to-Head Benchmarks

The only direct benchmark comparison recorded in the database is the Geekbench OpenCL test, and it favors the NVIDIA GeForce GT 755M. The GT 755M scores 4934, while the AMD FirePro W4190M scores 4505. That is a delta of 8.7%, meaning the NVIDIA part finishes nearly nine percent ahead in raw compute throughput as measured by this workload.

Looking at the broader database context, both cards sit in a similar performance tier. The FirePro W4190M lands at the 26th percentile of all GPUs, while the GT 755M sits just below at the 24th percentile. The average benchmark score for the AMD card is 4505, while the NVIDIA card averages 4033, which is dragged down by its additional Metal benchmark score of 3132. That OpenCL result, however, remains the only head-to-head data point, and it is a clear win for NVIDIA.

The margin is not trivial. An 8.7% gap in a synthetic compute test often translates into noticeable differences in real-world OpenCL-accelerated applications. The FirePro card’s nearest rivals in the database are the AMD Radeon R7 M260 at 4499 (0.1% behind), the Intel HD Graphics P530 at 4560 (1.2% ahead), the AMD Radeon RX 560 at 4569 (1.4% ahead), and the AMD Radeon R5 M230 at 4577 (1.6% ahead). The W4190M is essentially flanked by a cluster of low-end mobile and integrated parts, which underscores its modest standing.

For the GT 755M, the nearest rivals are the AMD FirePro M4150 at 4013 (0.5% behind), the Intel HD Graphics 630 at 4075 (1% ahead), the AMD Radeon HD 6850 X2 at 3977 (1.4% behind), and the AMD Radeon RX 9060 XT 8 GB at 4093 (1.5% ahead). The NVIDIA card’s average score of 4033 puts it in a similar neighborhood, though its OpenCL peak of 4934 is substantially higher than its average, indicating that the Metal test pulls the figure down. The database shows one win for the GT 755M and zero for the FirePro W4190M in direct head-to-head comparisons.

The Verdict

From the recorded data, the NVIDIA GeForce GT 755M is the stronger GPU in compute performance. Its 4934 OpenCL score beats the FirePro W4190M’s 4505 by 8.7%, and that is the only benchmark where both cards appear side by side. If the choice hinges purely on measured performance, the GT 755M wins.

The FirePro W4190M does have one distinction: it supports DirectX 12 (11_1), whereas the GT 755M is limited to DirectX 12 (11_0). That is a feature-level difference, not a performance one, and it matters only for applications that specifically require 11_1 capabilities. For general compute and graphics workloads, the NVIDIA part’s higher clock speeds and larger texture and pixel throughput figures give it the edge.

The GT 755M also has a higher transistor count (1,270 million versus 950 million) and a larger die (118 mm² versus 77 mm²), which aligns with its stronger raw output. The FirePro card has a higher transistor density (12.3M per mm² versus 10.8M per mm²), indicating a denser design, but that does not translate into a benchmark win here.

Given the data, the GT 755M is the pick for users prioritizing OpenCL compute performance. The FirePro W4190M is only preferable if the specific DirectX feature level or the AMD Vulkan version matters, but the database shows no performance scenario where the AMD card wins.

Where Each One Wins

NVIDIA GeForce GT 755M wins on compute throughput. The OpenCL score of 4934 versus 4505 is a 8.7% advantage. The GT 755M also has higher pixel rate (8.160 GPixel/s versus 7.200 GPixel/s), higher texture rate (32.64 GTexel/s versus 21.60 GTexel/s), and higher FP32 throughput (783.4 GFLOPS versus 691.2 GFLOPS). Memory bandwidth is also higher at 86.40 GB/s versus 64.00 GB/s, despite both using a 128-bit bus and 2 GB of GDDR5. The NVIDIA card’s boost clock of 1020 MHz and base clock of 980 MHz both exceed the AMD part’s 900 MHz boost and 825 MHz base. Those hardware specifications align with the benchmark result.

AMD FirePro W4190M wins on architectural density and API level. The AMD chip packs 950 million transistors into 77 mm², yielding a density of 12.3M transistors per mm². The NVIDIA chip has 1,270 million transistors across 118 mm², for 10.8M per mm². The FirePro also supports DirectX 12 (11_1), one step above the GT 755M’s DirectX 12 (11_0). For Vulkan, the AMD card lists version 1.2.170, while the NVIDIA card lists 1.2.175, giving NVIDIA a slightly newer Vulkan revision. Both cards have 384 shading units, but the NVIDIA part has 32 texture mapping units and 16 ROPs, versus 24 TMUs and 8 ROPs for AMD.

The GT 755M also wins on bandwidth efficiency. Its memory runs at 1350 MHz (5.4 Gbps effective) versus the FirePro’s 1000 MHz (4 Gbps effective), producing 86.40 GB/s versus 64.00 GB/s. That is a 35% bandwidth advantage, which is significant for memory-bound workloads.

The FirePro W4190M wins on release timing and power rating. The AMD card launched later (November 2015 versus June 2013) and carries no listed TDP in the database, while the GT 755M is rated at 50 W. The absence of a TDP figure for the AMD part is notable, but the NVIDIA card’s 50 W rating is documented.

The two GPUs come from different architectural lineages. The AMD FirePro W4190M is built on GCN 1.0, with the chip codename Opal, and belongs to the FirePro Mobile (Wx100M) generation. The NVIDIA GeForce GT 755M uses the Kepler architecture, with the GK107 chip, and is part of the GeForce 700M generation.

Both are fabricated by TSMC on a 28 nm process, but the dies differ substantially. The AMD chip measures 77 mm² and contains 950 million transistors, giving it a density of 12.3 million transistors per mm². The NVIDIA chip is larger at 118 mm² and packs 1,270 million transistors, resulting in a lower density of 10.8 million per mm². The larger NVIDIA die correlates with its higher measured throughput.

The clock behavior also differs. The AMD card has a base clock of 825 MHz and a boost clock of 900 MHz. The NVIDIA card runs at 980 MHz base and 1020 MHz boost. The memory clocks are likewise different: AMD uses 1000 MHz (4 Gbps effective), while NVIDIA uses 1350 MHz (5.4 Gbps effective). The NVIDIA memory configuration yields 86.40 GB/s of bandwidth versus 64.00 GB/s for AMD.

The compute resources are unevenly distributed. Both have 384 shading units, but NVIDIA allocates 32 TMUs and 16 ROPs, while AMD has 24 TMUs and 8 ROPs. The NVIDIA part achieves a pixel rate of 8.160 GPixel/s and a texture rate of 32.64 GTexel/s. The AMD part reaches 7.200 GPixel/s and 21.60 GTexel/s. FP32 performance is 783.4 GFLOPS for NVIDIA and 691.2 GFLOPS for AMD.

The bus interfaces differ: the AMD card uses PCIe 3.0 x8, while the NVIDIA card uses PCIe 3.0 x16. Both are MXM modules with no power connectors, and both have display outputs described as portable device dependent.

API support shows a split. AMD offers DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. NVIDIA offers DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The TDP is listed only for the NVIDIA card at 50 W; the AMD card has no TDP entry in the database. The AMD card was released in November 2015, while the NVIDIA card came out in June 2013. Both are end-of-life products, with AMD’s predecessor being FirePro Mobility and successor Radeon Pro Mobile, and NVIDIA’s predecessor GeForce 600M and successor GeForce 800M.
