AMD Radeon R5 M240 vs NVIDIA GeForce GTX 650 Ti Boost Comparison

Where Each One Wins

The benchmark data splits cleanly between these two mobile and desktop oriented GPUs. The NVIDIA GeForce GTX 650 Ti Boost wins the only directly comparable test, the Geekbench OpenCL workload, with a 33.4% margin over the AMD Radeon R5 M240. That single head-to-head result defines the competitive picture: the GTX 650 Ti Boost is the faster card in raw compute throughput, and the R5 M240 trails by a substantial margin.

Looking at the broader benchmark suite, the GTX 650 Ti Boost also has results in Geekbench Metal and Geekbench Vulkan, scoring 4858 and 10041 respectively, while the R5 M240 only has a recorded OpenCL score. The GTX 650 Ti Boost's average benchmark score across all recorded tests is 8067, placing it in the 42nd percentile of all GPUs in the database. The R5 M240's average score is 6975, which lands it in the 39th percentile. This percentile gap, while not enormous, confirms that the GTX 650 Ti Boost sits slightly higher in the overall performance distribution.

The GTX 650 Ti Boost's nearest rivals in the database are the NVIDIA GRID K2 (average score 8080, just 0.2% higher), the NVIDIA GeForce GTX 650 Ti (8053, 0.2% lower), the NVIDIA GeForce GTX 880M (8040, 0.3% lower), and the NVIDIA Quadro P5000 (8039, 0.3% lower). This clustering suggests the GTX 650 Ti Boost performs in a tight band around the 8000 mark, with no rival more than 0.3% away in either direction. The R5 M240, by contrast, sits near the NVIDIA GeForce GTX 675M (6946, 0.4% lower), the NVIDIA GeForce GTX 680M (7023, 0.7% higher), and the NVIDIA T600 (7035, 0.8% higher), with the AMD FirePro M5100 (6830) trailing by 2.1%. In both cases, the closest rivals are within a couple of percent, which underlines how tightly packed this performance tier is.

For use cases, the GTX 650 Ti Boost is the clear pick for any workload that stresses OpenCL compute, given its 33.4% advantage. The R5 M240 does not win any recorded benchmark, so there is no measured scenario in the database where it comes out ahead. Its strengths, if any, would have to be inferred from its lower power footprint and smaller die, but the benchmark data does not support a performance win.

Architecture Differences

The two GPUs come from different architectural lineages. The GTX 650 Ti Boost uses NVIDIA's Kepler architecture, built around the GK106 chip, while the R5 M240 uses AMD's GCN 1.0 architecture with the Jet chip. Both are fabricated on TSMC's 28 nm process, so the manufacturing node is identical. The transistor counts, however, diverge sharply: the GTX 650 Ti Boost packs 2,540 million transistors on a 221 mm² die, giving a transistor density of 11.5M per mm². The R5 M240 contains just 690 million transistors on a 56 mm² die, with a density of 12.3M per mm². The GTX 650 Ti Boost is therefore a much larger and more complex chip, roughly 4 times the transistor count and nearly 4 times the die area.

The compute resources reflect this gap. The GTX 650 Ti Boost has 768 shading units, 64 texture mapping units, and 24 ROPs. The R5 M240 has 320 shading units, 20 TMUs, and 8 ROPs. Pixel fill rate for the GTX 650 Ti Boost is 16.51 GPixel/s versus 8.24 GPixel/s for the R5 M240. Texture fill rate is 66.05 GTexel/s versus 20.60 GTexel/s. Floating point performance (FP32) is 1.585 TFLOPS for the NVIDIA part versus 659.2 GFLOPS for the AMD part. Every raw throughput metric favors the GTX 650 Ti Boost by a wide margin.

Clock behavior also differs. The GTX 650 Ti Boost has a base clock of 980 MHz and a boost clock of 1032 MHz, while the R5 M240 runs at 1000 MHz base and 1030 MHz boost. The AMD card starts slightly higher at base but the boost clocks are nearly identical. Memory configurations are completely different: the GTX 650 Ti Boost uses 2 GB of GDDR5 on a 192-bit bus, delivering 144.2 GB/s of bandwidth, while the R5 M240 uses 1024 MB of DDR3 on a 64-bit bus, delivering only 14.40 GB/s. The NVIDIA card's memory bandwidth is exactly 10 times higher. The memory clock is listed as 1502 MHz (6 Gbps effective) for the GTX 650 Ti Boost versus 900 MHz (1800 Mbps effective) for the R5 M240.

The bus interface also differs: PCIe 3.0 x16 for the GTX 650 Ti Boost versus PCIe 3.0 x8 for the R5 M240. API support shows a minor split, with the GTX 650 Ti Boost at DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175, while the R5 M240 supports DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. The DirectX feature level is slightly higher on the AMD side, but both are effectively modern in API terms. The GTX 650 Ti Boost has a 134 W TDP, a dual-slot design, and requires a 1x 6-pin power connector with a 300 W suggested PSU. The R5 M240 has no recorded TDP, slot width, power connector, or PSU recommendation, which is typical for a low-power mobile part.

The Verdict

The data points to a straightforward conclusion: the NVIDIA GeForce GTX 650 Ti Boost is the stronger GPU in every measured category. It wins the only shared benchmark, the Geekbench OpenCL test, by 33.4%. It has a higher average benchmark score (8067 versus 6975). It sits at a higher percentile (42 versus 39). Its raw compute specifications, memory bandwidth, and fill rates all exceed the AMD part by multiples.

The R5 M240 is not without a role, but the database does not record a single benchmark win for it. The only question is whether the use case favors the AMD chip despite the numbers. Given that the GTX 650 Ti Boost carries double the memory capacity (2 GB versus 1024 MB, technically the AMD card's 1024 MB is exactly 1 GB, so the NVIDIA card has double), 10 times the memory bandwidth, and more than double the shading units, the R5 M240's smaller footprint and lower complexity (690 million transistors versus 2,540 million, a 56 mm² die versus 221 mm²) suggest it belongs in a different tier of hardware entirely.

For a user choosing between the two, the GTX 650 Ti Boost wins on measured performance and every recorded metric. The R5 M240 should only be considered if the workload does not rely on OpenCL or any of the GTX 650 Ti Boost's strengths, but the benchmark data offers no such scenario where the AMD card comes out ahead. The verdict, strictly from the measurements, is NVIDIA.

Head-to-Head Benchmarks

The only directly comparable benchmark between the two GPUs is the Geekbench OpenCL test. The GTX 650 Ti Boost scores 9302, and the R5 M240 scores 6975. The delta is 33.4% in favor of the NVIDIA card. This is a decisive margin in a compute workload that stresses general purpose GPU execution, memory bandwidth, and shading throughput. A 33.4% lead is more than enough to classify the GTX 650 Ti Boost as the faster card for OpenCL applications.

The GTX 650 Ti Boost also has recorded scores in Geekbench Metal (4858) and Geekbench Vulkan (10041), but the R5 M240 has no corresponding results in those tests, so no direct comparison is possible. The GTX 650 Ti Boost's average score across all benchmarks is 8067, while the R5 M240's average is 6975, a difference of 15.7%. That average includes the Vulkan and Metal results for the NVIDIA card, which are higher than its OpenCL score, pulling its average up. The R5 M240's average is based solely on its OpenCL result.

The nearest rival data reinforces the tier separation. The GTX 650 Ti Boost competes with cards like the GRID K2, GTX 650 Ti, GTX 880M, and Quadro P5000, all within 0.3% of its average score. The R5 M240 competes with the GTX 675M, GTX 680M, T600, and FirePro M5100, with deltas ranging from 2.1% below to 0.8% above. There is no overlap between these rival groups, which shows that the two GPUs occupy distinct performance bands in the database.
