AMD Radeon 740M vs AMD Radeon Pro 450 Comparison

Head-to-Head Benchmarks

The recorded data from the database shows a clear overall victory for the AMD Radeon 740M, winning both head-to-head benchmark comparisons. The two GPUs were tested in Geekbench OpenCL and Geekbench Vulkan workloads, and the 740M outperformed the Radeon Pro 450 in each instance.

In the Geekbench OpenCL test, the AMD Radeon 740M scored 10,172 points against the Radeon Pro 450’s 9,002 points. This represents a 13% advantage for the newer integrated part. While this is a notable margin, it is not overwhelming, suggesting that in compute-heavy, general-purpose workloads, the 740M holds a solid but not dominant lead.

The gap widens dramatically in the Geekbench Vulkan test. Here, the AMD Radeon 740M scored 15,568 points, while the Radeon Pro 450 managed 10,518 points. This translates to a 48% delta in favor of the 740M. This is a substantial performance gap, indicating that the 740M’s architecture is far more efficient at handling modern, low-level graphics APIs. The Vulkan result is the single biggest differentiator between the two products in the entire benchmark set.

Looking at the average benchmark scores across all recorded tests, the 740M averages 12,870 points, which places it in the 53rd percentile among all GPUs in the database. The Radeon Pro 450 averages 10,804 points, sitting in the 49th percentile. The 740M’s nearest rivals in the database include the AMD FirePro W5100 with an average score of 12,847 (a 0.2% difference), the AMD Radeon Pro 455 at 12,831 (0.3% difference), and the NVIDIA GeForce GTX 590 at 12,830 (0.3% difference). The AMD Radeon RX 580 sits slightly above it at 12,928, a 0.4% delta. This places the 740M in a competitive bracket with older discrete desktop cards.

For the Radeon Pro 450, its nearest rivals are the NVIDIA Quadro K2200 at 10,761 (a 0.4% difference), the NVIDIA GeForce MX350 at 10,883 (a 0.7% difference in the other direction), and the NVIDIA GeForce GTX 560 Ti at 10,690 (a 1.1% difference). The AMD Radeon RX 6600S trails at 10,629, a 1.7% delta. The Radeon Pro 450’s average score is clearly lower, and its percentile ranking confirms it sits below the midpoint of the database.

Where Each One Wins

The benchmark results indicate a specific split in strengths. The AMD Radeon 740M wins in both compute and graphics API workloads, but the magnitude of the wins differs significantly.

In OpenCL, which often reflects raw compute throughput and general-purpose processing, the 740M wins by 13%. This is a meaningful advantage, likely stemming from its much higher FP32 throughput and advanced architecture. The 740M delivers 2.867 TFLOPS of FP32 performance, while the Radeon Pro 450 delivers 1,024.0 GFLOPS (or 1.024 TFLOPS). This nearly threefold difference in raw floating-point capability explains the OpenCL margin, although the actual benchmark delta is smaller, suggesting other bottlenecks.

In Vulkan, the 740M’s win expands to 48%. This is a massive gap and points to architectural superiority in handling modern graphics pipelines. The 740M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, whereas the Radeon Pro 450 supports DirectX 12 (12_0) and Vulkan 1.3. The newer feature set, combined with a smaller but more efficient core design, gives the 740M a decisive edge in this API.

The Radeon Pro 450 does have one recorded benchmark that the 740M does not: a Geekbench Metal score of 12,893. However, since the 740M has no Metal benchmark recorded in the database, this cannot be compared directly. The Pro 450’s wins are therefore limited to a platform-specific API that is not measured for the 740M.

For users prioritizing modern cross-platform graphics APIs like Vulkan, the 740M is the clear choice. For workloads that rely on Metal (typically Apple ecosystem applications), the Pro 450 has a recorded score, but the 740M’s compatibility with that API is not documented in the database.

Architecture Differences

The two GPUs come from entirely different architectural generations and design philosophies. The AMD Radeon 740M is built on RDNA 3.0, using the Phoenix2 chip, and belongs to the Navi III IGP (Phoenix) generation. It is manufactured on a 4 nm process by TSMC, packing 20,900 million transistors into a 137 mm² die. This results in a transistor density of 152.6 million per mm², an incredibly high figure that reflects the advanced node.

In contrast, the AMD Radeon Pro 450 uses the Baffin chip with GCN 4.0 architecture, belonging to the Radeon Pro Mac (400 Series) generation. It is manufactured on a 14 nm process by GlobalFoundries, containing only 3,000 million transistors on a 123 mm² die. Its transistor density is a much lower 24.4 million per mm². The generational leap from 14 nm to 4 nm is stark, and it explains why the 740M can offer far higher performance in a smaller power envelope.

The core configurations also differ significantly. The 740M has 256 shading units, 16 texture mapping units, and 8 render output units. It also includes 4 ray tracing cores, a feature entirely absent from the Radeon Pro 450. The Pro 450, on the other hand, has 640 shading units, 40 TMUs, and 16 ROPs. Despite having more of these traditional units, the Pro 450’s older GCN design is less efficient per unit. The 740M’s pixel rate is 22.40 GPixel/s compared to the Pro 450’s 12.80 GPixel/s. Its texture rate is 44.80 GTexel/s versus 32.00 GTexel/s for the Pro 450.

The FP16 performance also shows a difference in approach. Both GPUs list FP16 at a 1:1 ratio with FP32, meaning neither has a dedicated half-rate or boosted FP16 path. The 740M delivers 2.867 TFLOPS in FP16, while the Pro 450 delivers 1,024.0 GFLOPS.

Specification Differences

The specification sheets reveal several key differences beyond the architecture. The most obvious is the memory subsystem. The AMD Radeon 740M uses system shared memory, with its size, type, bus width, and bandwidth all listed as system dependent. This means it relies on the host system’s RAM, and performance will vary based on the platform’s memory configuration.

The AMD Radeon Pro 450, by contrast, has dedicated memory: 2 GB of GDDR5 on a 128-bit bus, providing 81.28 GB/s of bandwidth. Its memory clock is listed as 1270 MHz, or 5.1 Gbps effective. This dedicated memory gives the Pro 450 a fixed and predictable memory performance, which can be an advantage in certain workloads that do not scale well with system memory bandwidth.

Clock speeds also differ. The 740M has a base clock of 800 MHz and a boost clock of 2800 MHz. The Pro 450’s base and boost clocks are not listed in the database, so no direct comparison can be made on that front. The memory clock for the 740M is listed as system shared, meaning it is dependent on the installed RAM.

Power consumption is another differentiator. The 740M has a TDP of 45 W, while the Pro 450 has a TDP of 35 W. The 740M is an integrated graphics processor (IGP) with a slot width of IGP and no power connectors. The Pro 450 is an MXM module, a form factor designed for laptops and mobile workstations. Its power connectors are not specified.

The bus interface also differs: the 740M uses PCIe 4.0 x8, while the Pro 450 uses PCIe 3.0 x8. The newer PCIe standard provides double the bandwidth per lane, which can benefit the 740M when accessing system memory. Display outputs are motherboard dependent for the 740M and portable device dependent for the Pro 450.

Production status and release dates are also distinct. The 740M is listed as active, released on 2024-01-30. The Pro 450 is end-of-life, released on 2016-10-29. The 740M’s predecessor is listed as Navi II IGP, and its successor is Navi III IGP. The Pro 450 has no recorded predecessor or successor.
