AMD Radeon R7 M440 vs NVIDIA GeForce GTX 770M Comparison

Where Each One Wins

The recorded benchmark data splits cleanly between these two mobile GPUs. The NVIDIA GeForce GTX 770M takes the only head-to-head test available, and it does so decisively. In Geekbench OpenCL, the GTX 770M scores 8,552 points against the Radeon R7 M440's 5,214 points, a 64% advantage. That is not a marginal lead; it is a category gap. The GTX 770M is in a different performance tier entirely.

The AMD Radeon R7 M440 does have a Vulkan score of 5,751 in the database, but there is no corresponding Vulkan result for the GTX 770M in the head-to-head set, so no direct comparison can be made there. The GTX 770M also posts a Geekbench Metal score of 3,448, a test the R7 M440 does not appear in. For any workload that leans on OpenCL, the NVIDIA part is the clear choice. The data does not show any test where the R7 M440 wins outright.

Looking at average benchmark scores, the GTX 770M sits at 6,000, while the R7 M440 trails at 5,483. That is roughly a 9.4% gap in aggregate performance. The percentile placement reinforces this: the GTX 770M ranks in the 35th percentile of all GPUs, while the R7 M440 sits in the 32nd. Neither is a high-end part, but the GTX 770M consistently lands above its AMD rival.

Architecture Differences

These two chips come from different design philosophies and different eras. The GTX 770M uses the GK106 chip built on NVIDIA's Kepler architecture, fabricated on a 28 nm TSMC process. It packs 2,540 million transistors into a 221 mm² die, giving a transistor density of 11.5M per mm². The R7 M440 uses AMD's Meso chip with GCN 3.0 architecture, also on a 28 nm TSMC process, but with 1,550 million transistors on a smaller 125 mm² die, yielding a higher density of 12.4M per mm².

The compute resources differ sharply. The GTX 770M has 960 shading units, 80 texture mapping units, and 24 ROPs. The R7 M440 has only 320 shading units, 20 TMUs, and 8 ROPs. That is a 3x advantage in shaders and a 4x advantage in TMUs for the NVIDIA part. The pixel and texture rates reflect this: the GTX 770M delivers 15.94 GPixel/s and 63.76 GTexel/s, while the R7 M440 manages just 7.128 GPixel/s and 17.82 GTexel/s.

Memory architecture is another major divider. The GTX 770M uses 3 GB of GDDR5 on a 192-bit bus, yielding 96.19 GB/s of bandwidth. The R7 M440 uses 4 GB of DDR3 on a 64-bit bus, which produces only 14.40 GB/s. The GTX 770M's memory subsystem is over 6.5 times faster in raw bandwidth, a massive difference for texture-heavy scenes and higher resolutions.

Clock behavior also differs. The GTX 770M has a base clock of 706 MHz and a boost clock of 797 MHz, with memory running at 1002 MHz (4 Gbps effective). The R7 M440 lists no base or boost clocks in the database, only a memory clock of 900 MHz (1800 Mbps effective). The NVIDIA part also has a defined TDP of 75 W, while the R7 M440's TDP is not recorded.

API support shows a notable split. The GTX 770M supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The R7 M440 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. The AMD part has a higher DirectX feature level, which could matter for certain modern titles, but its raw throughput is far lower.

FAQ

Q: Which GPU is faster in OpenCL workloads?

A: The NVIDIA GeForce GTX 770M scores 8,552 in Geekbench OpenCL, which is 64% higher than the AMD Radeon R7 M440's 5,214. The GTX 770M wins the only direct head-to-head benchmark recorded.

Q: Does the Radeon R7 M440 have any advantage in memory capacity?

A: Yes, the R7 M440 has 4 GB of DDR3 memory, while the GTX 770M has 3 GB of GDDR5. However, the GTX 770M's memory bandwidth is far higher at 96.19 GB/s versus 14.40 GB/s, so the capacity advantage does not translate into a performance win.

Q: Which GPU has better API support?

A: The R7 M440 supports DirectX 12 (12_0), while the GTX 770M supports DirectX 12 (11_0). Both support OpenGL 4.6, and the GTX 770M has a slightly newer Vulkan version at 1.2.175 versus 1.2.170.

Q: What are the physical differences between the two?

A: The GTX 770M is an MXM Module with a 75 W TDP and no power connectors. The R7 M440 is an IGP with no recorded TDP. Both are designed for portable devices, but the GTX 770M is a discrete module while the R7 M440 is integrated.

Q: Which GPU is more recent?

A: The GTX 770M was released on May 29, 2013, while the R7 M440 came later on May 14, 2016. Despite being newer, the R7 M440 does not outperform the older NVIDIA part in the recorded benchmarks.

The GTX 770M leads in nearly every compute and memory metric. The only specification where the R7 M440 wins is memory capacity (4 GB vs 3 GB) and DirectX feature level (12_0 vs 11_0). The R7 M440 also has a higher transistor density per mm², but that is a design metric, not a performance one.

Head-to-Head Benchmarks

The database contains one direct comparison: Geekbench OpenCL. The GTX 770M scores 8,552, and the R7 M440 scores 5,214. That is a 64% delta in favor of NVIDIA. To put that in context, the GTX 770M's nearest rival is the AMD Radeon RX 6400 with an average score of 6,001, which is nearly identical. The R7 M440's nearest rival is the NVIDIA GeForce MX130 at 5,508, a mere 0.5% above its score. In other words, the GTX 770M performs like a mid-range desktop-class part, while the R7 M440 sits among entry-level mobile chips.

The GTX 770M also has a Geekbench Metal score of 3,448, though the R7 M440 has no Metal result on record. The R7 M440 does have a Vulkan score of 5,751, which is higher than its OpenCL score, but there is no Vulkan result for the GTX 770M to compare against. Even so, the OpenCL gap is so large that it is difficult to imagine the R7 M440 closing it in any API.

In terms of raw throughput, the GTX 770M delivers 1.530 TFLOPS of FP32 compute, while the R7 M440 manages 570.2 GFLOPS. That is a 2.68x advantage for NVIDIA. The pixel rate is 15.94 GPixel/s versus 7.128 GPixel/s, and the texture rate is 63.76 GTexel/s versus 17.82 GTexel/s. Every measurable compute metric points the same direction.

The Verdict

The data is unambiguous. The NVIDIA GeForce GTX 770M outperforms the AMD Radeon R7 M440 in the only shared benchmark, and it does so by a wide margin. The 64% OpenCL lead is backed by a 9.4% advantage in average benchmark score and a three-point higher percentile ranking. For anyone choosing between these two for a laptop upgrade or a used system purchase, the GTX 770M is the only sensible pick if raw performance is the priority.

The R7 M440 is not without merits, but they are narrow. It has 4 GB of memory versus 3 GB, which can help in games that are VRAM-hungry at lower settings. It also supports DirectX 12 (12_0), which is a more complete feature set than the GTX 770M's 12 (11_0). And it is a newer design, released in 2016 versus 2013. But none of that overcomes the fact that the GTX 770M has 3x the shading units, 4x the TMUs, and nearly 7x the memory bandwidth.

For a builder assembling a portable gaming rig from older parts, the GTX 770M's MXM form factor and 75 W TDP make it a straightforward drop-in for compatible laptops. The R7 M440, being an IGP, is more of a budget integrated solution. The benchmark results show that NVIDIA's older Kepler chip simply has more headroom. The verdict: buy the GTX 770M if you can, and only settle for the R7 M440 if the system requires an integrated GPU or the memory capacity is a hard constraint. The performance gap is too large to justify the AMD part on any other basis.
