AMD Radeon 760M vs NVIDIA GeForce GTX 580M Comparison

# Head-to-Head Benchmarks

The benchmark data delivers a decisive verdict: the AMD Radeon 760M crushes the NVIDIA GeForce GTX 580M in the only directly comparable test. In Geekbench OpenCL, the Radeon 760M scores 20,255 against the GTX 580M's 6,389. That is a 68.5% advantage for the AMD part—a margin so large that it redefines the competitive landscape between these two GPUs. The GTX 580M does not win a single head-to-head benchmark in this dataset; the Radeon 760M claims the sole win.

Context from the nearest rivals reinforces how one-sided this matchup is. The GTX 580M's average benchmark score of 6,389 places it exactly level with the NVIDIA GeForce GTX 460 SE (6,389, 0% delta), and only 0.9% above the AMD Radeon Pro WX 4100 (6,330). Its percentile ranking of 37 means it sits below the median of all GPUs in the database. Meanwhile, the Radeon 760M's average score of 6,019 is dragged down by its PassMark DirectX tests—scores of 19, 52, 25, and 65 in DirectX 10, 11, 12, and 9 respectively—but its Geekbench OpenCL result of 20,255 is the standout figure. The Radeon 760M's nearest rivals include the AMD Radeon RX 6400 (6,001, 0.3% ahead) and the NVIDIA GeForce GTX 770M (6,000, 0.3% ahead), showing that its average is competitive with dedicated mobile GPUs from a later era.

The gap in raw compute is staggering. The GTX 580M delivers 952.3 GFLOPS of FP32 performance, while the Radeon 760M delivers 5.323 TFLOPS—over five times more. Even accounting for the GTX 580M's 384 shading units versus the Radeon 760M's 512, the architectural efficiency difference is enormous.

# Architecture Differences

These two GPUs come from fundamentally different eras and design philosophies. The NVIDIA GeForce GTX 580M is built on the Fermi 2.0 architecture, fabricated on TSMC's 40 nm process node with a die size of 332 mm² and 1,950 million transistors. That translates to a transistor density of 5.9 million per mm². The AMD Radeon 760M, by contrast, uses the RDNA 3.0 architecture on TSMC's 4 nm node, packing 25,390 million transistors into a 178 mm² die—a density of 142.6 million per mm². The Radeon 760M crams more than 13 times the transistors into roughly half the silicon area.

Memory configurations could not be more different. The GTX 580M has a dedicated 2 GB of GDDR5 memory on a 256-bit bus, yielding 96.00 GB/s of bandwidth and a memory clock of 750 MHz (3 Gbps effective). The Radeon 760M uses System Shared memory, with its bandwidth listed as System Dependent—it has no dedicated VRAM and relies on the host system's memory, which is both a flexibility and a limitation depending on the platform.

Clock behavior also diverges sharply. The GTX 580M's base and boost clocks are not listed in the data, but its memory clock is fixed. The Radeon 760M has a base clock of 800 MHz and a boost clock of 2,599 MHz—a massive 1,799 MHz boost range that reflects modern power management and thermal headroom. The Radeon 760M also features 8 ray tracing cores, a technology entirely absent from the Fermi-based GTX 580M.

The Radeon 760M's FP16 performance matches its FP32 at 5.323 TFLOPS (1:1 ratio), while the GTX 580M has no listed FP16 capability. The Radeon 760M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the GTX 580M is limited to DirectX 12 (11_0) with no Vulkan support listed. Both support OpenGL 4.6.

Form factors are as different as the architectures. The GTX 580M is an MXM Module with an MXM-B (3.0) bus interface and no power connectors, drawing 100 W. The Radeon 760M is an IGP (integrated graphics processor) on a PCIe 4.0 x8 interface, also with no power connectors, but drawing just 15 W—a fraction of the NVIDIA part's power envelope.

# Where Each One Wins

The AMD Radeon 760M wins everywhere that matters in this comparison. Its Geekbench OpenCL score of 20,255 is more than three times the GTX 580M's 6,389, making it the clear choice for any compute-oriented workload, including OpenCL acceleration. Its FP32 throughput of 5.323 TFLOPS versus 952.3 GFLOPS means it processes floating-point math over five times faster. The Radeon 760M's texture rate of 83.17 GTexel/s and pixel rate of 41.58 GPixel/s dwarf the GTX 580M's 39.68 GTexel/s and 9.920 GPixel/s respectively—critical for gaming and graphics rendering.

The Radeon 760M's ray tracing cores give it hardware-accelerated ray tracing, a feature the GTX 580M lacks entirely. For modern games that leverage DirectX 12 Ultimate features, the Radeon 760M is the only viable option between these two. Its Vulkan 1.4 support also opens the door to modern cross-platform titles and compute workloads that the GTX 580M cannot access.

The NVIDIA GeForce GTX 580M's only advantages are structural rather than performance-based. It has a dedicated 2 GB GDDR5 frame buffer with 96.00 GB/s of bandwidth, which can be beneficial in scenarios where system memory bandwidth is constrained or where the host system has slow RAM. Its 256-bit memory bus is wider than the Radeon 760M's System Shared configuration, which may help in certain memory-bandwidth-sensitive tasks. However, these advantages are theoretical in the context of the benchmark data, which shows no test where the GTX 580M wins.

The GTX 580M's 64 TMUs versus the Radeon 760M's 32 TMUs is another hardware advantage, but the Radeon's much higher clock speeds and architectural efficiency more than compensate. The Radeon 760M's 16 ROPs are half the GTX 580M's 32, yet its pixel rate is over four times higher, demonstrating the massive per-clock improvements in RDNA 3.0.

# The Verdict

The data leaves no room for ambiguity: the AMD Radeon 760M is the superior GPU in nearly every measurable way. Its Geekbench OpenCL score of 20,255 obliterates the GTX 580M's 6,389, and its FP32 throughput of 5.323 TFLOPS is over five times higher. The Radeon 760M achieves this while consuming just 15 W—a fraction of the GTX 580M's 100 W—and on a 4 nm process that fits 25,390 million transistors into a 178 mm² die.

Who should pick the NVIDIA GeForce GTX 580M? Essentially no one building or buying a GPU today. It is end-of-life, lacks ray tracing, supports only DirectX 12 (11_0), and is outperformed by a factor of three in the sole head-to-head benchmark. Its dedicated 2 GB GDDR5 memory and 256-bit bus are its only hardware advantages, but these do not translate into any benchmark victory.

Who should pick the AMD Radeon 760M? Anyone seeking a modern, efficient integrated GPU for a laptop or compact system. It delivers ray tracing, DirectX 12 Ultimate, Vulkan 1.4, and compute performance that places it in the same average-score neighborhood as dedicated GPUs like the AMD Radeon RX 6400 and NVIDIA GeForce GTX 770M. Its 15 W power envelope makes it viable for thin-and-light designs, and its active production status means ongoing driver support and availability.

The verdict is simple: the AMD Radeon 760M is the clear winner. The GTX 580M is a relic of the Fermi era, relevant only as a historical artifact. The benchmark data confirms that modern integrated graphics have surpassed dedicated GPUs from a decade prior—and done so with a fraction of the power draw.
