AMD Radeon RX 560 vs NVIDIA GeForce GT 755M Comparison

Head-to-Head Benchmarks

The AMD Radeon RX 560 dominates the NVIDIA GeForce GT 755M in the two recorded head-to-head comparisons. In Geekbench Metal, the RX 560 scores 18,941 against the GT 755M's 3,132, a 504.8% advantage. This is not a marginal gap; it is a multi-generational leap in compute performance. The OpenCL result tells the same story: 16,472 for the RX 560 versus 4,934 for the GT 755M, a 233.8% lead. In both tests, the RX 560 wins outright, and the database records zero wins for the GT 755M.

The average benchmark score reinforces the hierarchy. The RX 560 posts an average of 4,569 across all recorded benchmarks, while the GT 755M averages 4,033. That is a 13.3% overall gap, smaller than the compute tests suggest because the RX 560's PassMark scores pull its average down relative to its Geekbench results. Still, the direction is consistent: the RX 560 leads in every category where both have data.

The percentile rankings are close: the RX 560 sits at the 26th percentile among all GPUs, the GT 755M at the 24th. Both are entry-level parts by modern standards, but the RX 560's raw compute advantage is substantial. The nearest rivals for each card show how tight the mid-range field is. The RX 560's closest competitor is the AMD Radeon R5 M230 at 4,577 average score, just 0.2% behind, followed by the Intel HD Graphics P530 at 4,560, only 0.2% ahead of the RX 560. The GT 755M's nearest rival is the AMD FirePro M4150 at 4,013, 0.5% behind, with the Intel HD Graphics 630 at 4,075, 1% ahead.

These rivalries matter for context. The RX 560, despite its dominant head-to-head margin over the GT 755M, is not far from integrated graphics in average score. The GT 755M, meanwhile, is bracketed by a FirePro mobile part and an Intel iGPU. Neither card is a performance leader, but the RX 560 is clearly the stronger of the two.

Where Each One Wins

The RX 560 wins every recorded benchmark category. In Geekbench Metal, its 18,941 score is roughly six times the GT 755M's 3,132. In Geekbench OpenCL, the RX 560's 16,472 is more than three times the GT 755M's 4,934. The PassMark suite, which the GT 755M lacks entirely, shows the RX 560 scoring 3,671 in G3D, 1,437 in GPU compute, 485 in G2D, 57 in DirectX 9, 25 in DirectX 11, 21 in DirectX 12, and 16 in DirectX 10. These are not competitive numbers; they are simply absent for the GT 755M, which has no recorded PassMark results in the database.

The GT 755M has no wins anywhere. Its only recorded benchmarks are the two Geekbench tests, and it loses both by wide margins. For users considering the GT 755M for modern workloads, the data offers no category where it pulls ahead. The RX 560's 1024 shading units versus 384 for the GT 755M, and its 64 texture units versus 32, explain why the compute gap is so large. The RX 560 also doubles the memory capacity at 4 GB versus 2 GB, and memory bandwidth is 112.0 GB/s versus 86.40 GB/s.

The use-case split is therefore simple: the RX 560 is the choice for any workload that touches the GPU, whether that is compute, graphics, or memory-bound tasks. The GT 755M is only relevant in systems where power draw is a hard constraint, since it consumes 50 W versus 75 W for the RX 560, and even then the performance penalty is severe.

Architecture Differences

The two cards come from different foundries and process nodes. The RX 560 uses a 14 nm process at GlobalFoundries, while the GT 755M uses a 28 nm process at TSMC. The RX 560 packs 3,000 million transistors on a 123 mm² die, for a transistor density of 24.4 million per square millimeter. The GT 755M has 1,270 million transistors on a 118 mm² die, a density of 10.8 million per square millimeter. The RX 560's newer node allows more than double the transistor density, which directly enables its higher core counts.

The chip designs differ fundamentally. The RX 560 is built on GCN 4.0 architecture with the Polaris 21 chip, part of the Polaris generation (RX 500). The GT 755M uses the Kepler architecture with the GK107 chip, part of the GeForce 700M generation. GCN 4.0 is a later design with support for DirectX 12 at feature level 12_0, while Kepler supports DirectX 12 at the lower 11_0 feature level. Both support OpenGL 4.6, but Vulkan support differs: the RX 560 reaches Vulkan 1.3, the GT 755M only 1.2.175.

Core counts favor the RX 560 overwhelmingly. It has 1,024 shading units, 64 texture mapping units, and 16 ROPs. The GT 755M has 384 shading units, 32 TMUs, and 16 ROPs. The ROP count is equal, but the RX 560's pixel rate is 20.40 GPixel/s versus 8.160 GPixel/s for the GT 755M, and its texture rate is 81.60 GTexel/s versus 32.64 GTexel/s. The FP32 compute is 2.611 TFLOPS for the RX 560, compared to 783.4 GFLOPS for the GT 755M. The RX 560 also has FP16 at 2.611 TFLOPS with a 1:1 ratio, while the GT 755M has no recorded FP16 capability.

Memory architecture is similar in bus width but different in capacity and speed. Both use a 128-bit bus and GDDR5 memory, but the RX 560 has 4 GB at 1750 MHz (7 Gbps effective) for 112.0 GB/s bandwidth, while the GT 755M has 2 GB at 1350 MHz (5.4 Gbps effective) for 86.40 GB/s. The RX 560's clock speeds are higher too: 1175 MHz base and 1275 MHz boost versus 980 MHz base and 1020 MHz boost.

Physical and interface differences also matter. The RX 560 is a dual-slot card with no power connectors, a 250 W suggested PSU, and a PCIe 3.0 x8 interface. It measures 170 mm or 6.7 inches in length. The GT 755M is an MXM module, portable-device dependent for display outputs, and uses PCIe 3.0 x16. It has no suggested PSU rating and no recorded dimensions. The RX 560 offers explicit display outputs (1x DVI, 1x HDMI 2.0b, 1x DisplayPort 1.4a), while the GT 755M's outputs depend entirely on the host laptop.

Release timing explains much of the gap. The GT 755M launched on 2013-06-24, and the RX 560 on 2017-04-17, nearly four years later. The RX 560's predecessor is Arctic Islands and its successor is Vega; the GT 755M's predecessor is GeForce 600M and its successor is GeForce 800M. Both are end-of-life products.

The Verdict

The data is unambiguous: the AMD Radeon RX 560 is the superior GPU in every recorded benchmark. Its Geekbench Metal score is six times higher, its OpenCL score is more than three times higher, and it has a 13.3% higher average benchmark score. The GT 755M offers no category where it outperforms the RX 560. The only advantages the GT 755M holds are a lower TDP (50 W versus 75 W) and a wider PCIe interface (x16 versus x8), but neither translates into a performance win in the recorded data.

Users who need compute performance should pick the RX 560. Its 2.611 TFLOPS FP32 throughput, 112.0 GB/s memory bandwidth, and 4 GB capacity make it viable for modern workloads. The GT 755M, with 783.4 GFLOPS and 2 GB of memory, is confined to older or lighter tasks. The RX 560 also has better API support: DirectX 12 at 12_0, Vulkan 1.3, and FP16 compute. The GT 755M lags in all three.

The GT 755M makes sense only in a laptop where the 50 W TDP is a hard limit and the MXM form factor is required. Even then, the performance gap is so large that any workload beyond basic graphics will struggle. The RX 560, despite being an entry-level desktop card at the 26th percentile, is the clear choice for anyone choosing between these two.
