AMD Radeon R7 M440 vs NVIDIA GeForce GTX 760M Comparison

# Head-to-Head Benchmarks

The benchmark data splits sharply between the two available tests, with each GPU taking one decisive victory. In Geekbench OpenCL, the NVIDIA GeForce GTX 760M scores 5604 against the AMD Radeon R7 M440’s 5214, a 7% advantage for NVIDIA. That margin is meaningful but not overwhelming—it places the GTX 760M in line with its nearest rivals, sitting 0.5% above the NVIDIA Quadro 4000M and 1.5% above the AMD Radeon R7 M260X, while trailing the GeForce 940M by 0.9% and the GeForce GTX 980M by 1.3%.

The Vulkan test flips the outcome decisively. The AMD Radeon R7 M440 posts 5751, compared to the GTX 760M’s 4868, yielding an 18.1% lead for AMD. This is a substantial gap, and it reflects a fundamental difference in API handling between the two architectures. The AMD part’s Vulkan score even exceeds its own OpenCL result by over 500 points, while the NVIDIA part drops by more than 700 points in Vulkan relative to its OpenCL performance. In aggregate, the AMD Radeon R7 M440 averages 5483 across both tests, landing in the 32nd percentile of all GPUs; the GTX 760M averages 5236, sitting at the 31st percentile. Despite the GTX 760M winning one test by a smaller margin and losing the other by a larger one, the average scores are close—a 4.7% difference in AMD’s favor.

The nearest-rival comparisons reinforce this split. The AMD Radeon R7 M440’s average of 5483 places it 0.3% above the NVIDIA Quadro M4000, 0.7% above the AMD Radeon 610M, and 0.5% below the NVIDIA GeForce MX130, with the GeForce GTX 765M just 0.3% higher. The GTX 760M’s 5236 average puts it 0.5% above the Quadro 4000M, 1.5% above the Radeon R7 M260X, and 0.9% below the GeForce 940M, with the GTX 980M 1.3% higher. Both parts are clustered tightly among their peers, indicating that neither holds a commanding position in its class—the differences are within a few percentage points across the board.

# Architecture Differences

The two GPUs come from different architectural lineages and different manufacturing eras. The AMD Radeon R7 M440 uses the Meso chip built on GCN 3.0 architecture, fabricated by TSMC on a 28 nm process. It packs 1,550 million transistors into a 125 mm² die, yielding a transistor density of 12.4 million per square millimeter. The NVIDIA GeForce GTX 760M uses the GK106S chip based on Kepler architecture, also manufactured by TSMC on 28 nm, but with a larger 221 mm² die containing 2,540 million transistors—a density of 11.5 million per square millimeter. The AMD chip achieves higher transistor density despite fewer total transistors, while the NVIDIA chip uses its larger die to house significantly more execution resources.

The compute configuration diverges sharply. The Radeon R7 M440 has 320 shading units, 20 texture mapping units, and 8 ROPs. The GTX 760M more than doubles the shading units to 768, triples the TMUs to 64, and doubles the ROPs to 16. This reflects in the fill rates: the AMD part delivers 7.128 GPixel/s pixel rate and 17.82 GTexel/s texture rate, while the NVIDIA part reaches 11.50 GPixel/s and 46.02 GTexel/s. The FP32 compute throughput tells the same story—570.2 GFLOPS for AMD versus 1,104.4 GFLOPS for NVIDIA, a 93.6% advantage for the Kepler part. Interestingly, the AMD Radeon R7 M440 lists FP16 performance at the same 570.2 GFLOPS with a 1:1 ratio, while the GTX 760M has no FP16 figure listed.

Memory architecture also differs fundamentally. The Radeon R7 M440 uses 4 GB of DDR3 on a 64-bit bus, with memory clocked at 900 MHz (1800 Mbps effective) and bandwidth of 14.40 GB/s. The GTX 760M uses 2 GB of GDDR5 on a 128-bit bus, with memory at 1002 MHz (4 Gbps effective) and bandwidth of 64.13 GB/s. The NVIDIA part has a 4.45x bandwidth advantage, which is consistent with its larger bus and faster memory type. Clock behavior differs too: the GTX 760M has a base clock of 628 MHz and a boost clock of 719 MHz, while the Radeon R7 M440 lists no base or boost clock figures, only memory clocks.

Power and physical specifications also separate the two. The GTX 760M has a TDP of 55 W and uses an MXM Module slot width with no power connectors required. The Radeon R7 M440 is an IGP (integrated graphics processor) with no TDP listed. Both use PCIe 3.0, but the AMD part runs at x8 lanes while the NVIDIA part uses x16. API support shows a notable split: the AMD Radeon R7 M440 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170; the GTX 760M supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The DirectX feature level difference—12_0 versus 11_0—helps explain the Vulkan performance gap.

# Where Each One Wins

The GTX 760M wins in raw compute and memory bandwidth. Its FP32 throughput of 1,104.4 GFLOPS nearly doubles the Radeon R7 M440’s 570.2 GFLOPS. Its texture rate of 46.02 GTexel/s is 2.58x higher, and its pixel rate of 11.50 GPixel/s is 1.61x higher. Memory bandwidth of 64.13 GB/s dwarfs the 14.40 GB/s of the AMD part. These advantages translate directly into the OpenCL benchmark, where the NVIDIA GPU takes a 7% lead. Workloads that stress traditional rasterization, texture sampling, and high-bandwidth memory access—such as legacy DirectX 11 titles or compute tasks using OpenCL—would favor the GTX 760M.

The Radeon R7 M440 wins in Vulkan performance, and it wins big. The 18.1% margin in that test is the largest head-to-head difference between the two. Its Vulkan score of 5751 is higher than its OpenCL score of 5214, indicating that the GCN 3.0 architecture handles Vulkan more efficiently than Kepler does. The GTX 760M’s Vulkan score of 4868 is substantially lower than its OpenCL score of 5604, a 13.1% drop. Modern titles that leverage Vulkan’s low-overhead API would likely see better relative performance on the AMD part, despite its lower raw compute specs. The AMD GPU also offers more VRAM at 4 GB versus 2 GB, which could matter for texture-heavy workloads that fit within the slower but larger memory pool.

The wins are split one apiece, but the magnitudes differ. The GTX 760M’s OpenCL win is a modest 7%, while the Radeon R7 M440’s Vulkan win is an emphatic 18.1%. In terms of average benchmark score, the AMD part edges ahead at 5483 versus 5236, a 4.7% advantage. The percentile rankings are nearly identical—32nd for AMD, 31st for NVIDIA—so neither GPU escapes the lower-middle tier of the overall distribution.

# The Verdict

From the data, the choice depends entirely on the workload. For OpenCL-based applications and legacy DirectX workloads, the NVIDIA GeForce GTX 760M is the stronger pick—its 7% OpenCL lead is backed by roughly double the FP32 throughput, more than double the texture rate, and over four times the memory bandwidth. The 2 GB GDDR5 memory, while smaller in capacity, provides 64.13 GB/s of bandwidth that the AMD part cannot approach. If the target software relies on these traditional paths, the GTX 760M delivers measurably better performance.

For Vulkan-based applications, the AMD Radeon R7 M440 is the clear winner. Its 18.1% Vulkan margin over the GTX 760M is the single largest delta in the head-to-head data, and its DirectX 12 (12_0) feature level suggests better support for modern API features. The 4 GB memory capacity also gives it headroom for larger assets, even if the bandwidth is a bottleneck. Users running modern Vulkan titles or future DirectX 12 applications should favor the AMD part.

Given that the average benchmark score slightly favors the AMD Radeon R7 M440 (5483 versus 5236) and that its Vulkan win is more than double the GTX 760M’s OpenCL win in percentage terms, the data leans toward the AMD part for general-purpose use. However, the gap is small—the 32nd and 31st percentiles are effectively tied, and the nearest-rival comparisons show both GPUs within a few percentage points of similar-class parts. Neither GPU is a dominant performer; each has a specific API where it shines. The GTX 760M suits OpenCL-centric workflows and older game libraries; the Radeon R7 M440 suits Vulkan-centric workloads and modern API adoption. The deciding factor should be the API profile of the software in question, not the raw specification sheet.
