AMD Radeon R7 M445 vs NVIDIA GeForce GTX 770M Comparison

Head-to-Head Benchmarks

The only direct benchmark comparison available in the database is Geekbench OpenCL, and the result is decisively one-sided. The NVIDIA GeForce GTX 770M scores 8552, while the AMD Radeon R7 M445 scores 5358. That is a 59.6% advantage for the NVIDIA part. This is not a marginal gap; it is a substantial performance chasm that places the two GPUs in entirely different performance tiers.

Looking at the broader database context, the GTX 770M holds an average benchmark score of 6000, which places it in the 35th percentile of all GPUs. The R7 M445, by contrast, averages 5358, sitting in the 31st percentile. The percentile gap is modest, but the average score difference of 642 points reflects the clear hierarchy established by the OpenCL test.

The nearest rivals for each card further illustrate the competitive landscape. The GTX 770M's closest competitor in the database is the AMD Radeon RX 6400, with an average score of 6001, a delta of 0%. The NVIDIA RTX PRO 6000 Blackwell Server sits at 5996 (0.1% behind), the AMD FirePro W4100 at 5987 (0.2% behind), and the NVIDIA Quadro K4000M at 5986 (0.2% behind). This cluster of scores within a 15-point range suggests that the GTX 770M's average benchmark result is essentially tied with several other GPUs, all within a hair of each other.

For the R7 M445, the nearest rival is the Intel UHD Graphics P630, which scores 5370, a delta of -0.2% relative to the AMD part. The NVIDIA GeForce 840M trails by 0.7% with a score of 5322, the GeForce 930A by 0.8% at 5317, and the GeForce GTX 980M by 0.9% at 5308. The R7 M445 is therefore the top performer in its immediate peer group, but the margins are tiny, all under 1%. This tells a different story from the head-to-head result: the R7 M445 is competitive with its immediate neighbors, while the GTX 770M is grouped with a set of higher-performing cards.

The head-to-head data shows one win for the GTX 770M and zero for the R7 M445. The OpenCL test is the only recorded comparison, and the NVIDIA card wins it by a wide margin. There is no Geekbench Metal score for the AMD part, so no additional comparison can be made on that front.

Architecture Differences

The two GPUs come from different architectural lineages. The GTX 770M is built on NVIDIA's Kepler architecture, using the GK106 chip, fabricated by TSMC on a 28 nm process. The R7 M445 uses AMD's GCN 3.0 architecture, built around the Meso chip, also on TSMC's 28 nm node. Both share the same process node and foundry, yet their designs diverge sharply.

The transistor counts tell a story of scale. The GK106 packs 2,540 million transistors on a die size of 221 mm², yielding a transistor density of 11.5 million per square millimeter. The Meso chip contains 1,550 million transistors on a 125 mm² die, giving a higher density of 12.4 million per square millimeter. Despite the smaller absolute numbers, the AMD chip is denser, indicating a more compact design per unit area.

The compute resources differ considerably. The GTX 770M has 960 shading units, 80 texture mapping units, and 24 render output units. The R7 M445 has 320 shading units, 20 TMUs, and 8 ROPs. These are roughly one-third to one-quarter of the NVIDIA card's counts, which explains the substantial performance gap in compute-heavy workloads.

Clock speeds complicate the picture. The AMD card runs at a base clock of 780 MHz with a boost of 920 MHz, while the NVIDIA card operates at 706 MHz base and 797 MHz boost. The R7 M445 has higher clocks on paper, but the GTX 770M's much larger shader array and wider memory bus more than compensate. Memory clocks are nearly identical: 1002 MHz for NVIDIA (4 Gbps effective) and 1000 MHz for AMD (4 Gbps effective). The memory subsystems, however, are very different.

The GTX 770M features 3 GB of GDDR5 on a 192-bit bus, delivering 96.19 GB/s of bandwidth. The R7 M445 has 4 GB of GDDR5 on a 64-bit bus, yielding just 32.00 GB/s. That is a threefold difference in memory bandwidth, a critical factor for texture-heavy and high-resolution workloads. The AMD card's larger capacity may help with larger datasets, but the narrow bus severely limits throughput.

The R7 M445 supports DirectX 12 (12_0), while the GTX 770M is limited to DirectX 12 (11_0). Both support OpenGL 4.6 and Vulkan, though with different version numbers: 1.2.175 for NVIDIA and 1.2.170 for AMD. The AMD card also lists FP16 support at 588.8 GFLOPS (1:1), while the NVIDIA card has no recorded FP16 capability. The GTX 770M's FP32 output is 1.530 TFLOPS, compared to 588.8 GFLOPS for the AMD part.

The bus interfaces differ as well: the GTX 770M uses MXM-B (3.0) as a removable module, while the R7 M445 is an integrated graphics processor (IGP) on PCIe 3.0 x8. The NVIDIA card has a TDP of 75 W with no power connectors required, while the AMD card has no recorded TDP figure.

Where Each One Wins

The GTX 770M wins decisively in raw compute performance. Its OpenCL score of 8552 versus 5358, a 59.6% lead, demonstrates clear superiority in general-purpose compute tasks. The 1.530 TFLOPS FP32 output, versus 588.8 GFLOPS, means the NVIDIA card handles floating-point workloads almost three times faster. Its 96.19 GB/s memory bandwidth versus 32.00 GB/s makes it the better choice for bandwidth-sensitive applications like high-resolution textures or large buffer operations. The higher texture rate of 63.76 GTexel/s versus 18.40 GTexel/s and pixel rate of 15.94 GPixel/s versus 7.360 GPixel/s also favor the NVIDIA card for graphics-intensive workloads.

The R7 M445 wins in areas of efficiency and compatibility. Its higher transistor density of 12.4M per mm² versus 11.5M per mm² suggests a more compact design. It supports DirectX 12 (12_0), while the GTX 770M is limited to 11_0, meaning the AMD card can run applications that require the newer feature level. The 4 GB memory capacity versus 3 GB gives it more headroom for large datasets, even though the narrow bus limits practical throughput. Its FP16 support at 588.8 GFLOPS (1:1) provides a capability the NVIDIA card lacks entirely. As an IGP, it is also more integrated into the system, whereas the GTX 770M is a removable MXM module.

The R7 M445 also holds its own within its peer group. Its nearest rivals are all within 0.9% of its average score, and it sits at the top of that cluster. The GTX 770M, by contrast, is tied with several other GPUs at the 6000-score mark, but those rivals are all higher-performing cards.

The Verdict

The data is unambiguous: the NVIDIA GeForce GTX 770M is the stronger GPU for raw performance. Its 59.6% lead in OpenCL, nearly three times the FP32 throughput, and triple the memory bandwidth make it the clear choice for users who need compute power. The 35th percentile ranking versus the R7 M445's 31st percentile, along with the 6000 versus 5358 average benchmark score, confirms this hierarchy.

Users who prioritize modern API support should consider the R7 M445. Its DirectX 12 (12_0) support and FP16 capability are features the GTX 770M cannot offer. The larger 4 GB memory capacity also provides more storage for textures or datasets, though the 64-bit bus will limit practical bandwidth.

The choice depends on workload. For compute-heavy tasks, gaming, or any application that stresses memory bandwidth, the GTX 770M is the superior option. For users on systems with limited power budgets or those requiring the latest DirectX feature level, the R7 M445 offers a viable alternative despite its lower performance.

The database shows one winner in head-to-head testing, and that winner is the NVIDIA card. The R7 M445's advantages are real but narrower, confined to specific features rather than overall performance. Buyers seeking maximum speed should choose the GTX 770M; those needing specific modern features or more memory capacity should evaluate the R7 M445.
