AMD Radeon R5 M435 vs Intel UHD Graphics 730 Comparison

Intel UHD Graphics 730 and AMD Radeon R5 M435 are both end-of-life integrated-class GPUs that land in the 33rd percentile of all GPUs, but the data shows they reach that tier through very different designs. The Intel part, built on Rocket Lake's Generation 12.1 architecture, edges out the older AMD GCN 1.0 part in the only shared benchmark, winning the Geekbench OpenCL test with a score of 5988 against 5859, a 2.2% margin. However, the R5 M435 counters with substantially higher raw shader counts and dedicated memory, making the choice between them dependent on whether the workload favors newer architecture features or fixed-function hardware resources.

Where Each One Wins

The Intel UHD Graphics 730 wins the only direct head-to-head benchmark recorded, the Geekbench OpenCL test, scoring 5988 versus 5859 for the Radeon R5 M435. This 2.2% advantage aligns with Intel's higher pixel rate of 10.40 GPixel/s and its support for DirectX 12 (12_1) and Vulkan 1.4, which are more recent API revisions than what AMD offers. The Intel GPU also benefits from a higher boost clock of 1300 MHz against AMD's 1030 MHz, and its 15 W TDP makes it a fit for power-constrained systems.

The Radeon R5 M435 counters in raw compute throughput, delivering 659.2 GFLOPS of FP32 performance versus Intel's 499.2 GFLOPS, a 32% advantage. Its dedicated 2 GB of GDDR5 memory with 36.00 GB/s bandwidth provides a fixed memory pool that does not compete with the CPU for system RAM, unlike the Intel part's system-shared configuration. AMD also fields more shading units (320 vs 192) and TMUs (20 vs 12), which can benefit workloads that scale with parallel execution units, even if the overall benchmark score does not reflect that advantage in the recorded test.

For users running modern API-dependent applications, Intel's Generation 12.1 architecture with Vulkan 1.4 support offers a forward-looking feature set. For those needing dedicated VRAM and higher raw FP32 throughput, the Radeon's GCN 1.0 design with its 690 million transistors on a 56 mm² die presents a more mature fixed-function approach, though its 28 nm process node is older than Intel's 14 nm+++ node.

Architecture Differences

The Intel UHD Graphics 730 is built on Rocket Lake silicon using Intel's Generation 12.1 architecture on a 14 nm+++ process node, fabricated in-house at Intel. It incorporates 192 shading units, 12 TMUs, and 8 ROPs, with a base clock of 300 MHz and a boost clock of 1300 MHz. The GPU relies entirely on system-shared memory, with the memory type, bus width, and bandwidth all marked as "System Shared" or "System Dependent," meaning performance scales with the host system's RAM configuration. Its API support includes DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, and it connects via a Ring Bus interface.

The AMD Radeon R5 M435 uses the Jet chip based on GCN 1.0 architecture, manufactured on a 28 nm process at TSMC. It packs 690 million transistors into a 56 mm² die, yielding a transistor density of 12.3M per mm². The GPU has 320 shading units, 20 TMUs, and 8 ROPs, with a base clock of 780 MHz and a boost clock of 1030 MHz. Its memory subsystem is entirely different: 2 GB of GDDR5 on a 64-bit bus with 36.00 GB/s bandwidth, clocked at 1125 MHz with 4.5 Gbps effective speed. The interface is PCIe 3.0 x8, and API support covers DirectX 12 (11_1), OpenGL 4.6, and Vulkan 1.2.170. Its predecessor is listed as Solar System, and its successor is Polaris Mobile.

The architectural gulf is substantial: Intel's newer Generation 12.1 on a smaller process node delivers higher clocks and better API compatibility, but AMD's GCN 1.0 design compensates with a wider array of compute units and a dedicated memory pipeline. Intel's FP16 throughput is 998.4 GFLOPS (2:1 ratio), while AMD lists no FP16 capability, indicating Intel's architecture is better suited to workloads that can leverage half-precision math.

Specification Differences

The two GPUs diverge on nearly every measurable specification except ROP count, which is 8 for both. Clock speeds differ significantly: Intel runs at 300 MHz base and 1300 MHz boost, while AMD runs at 780 MHz base and 1030 MHz boost, giving Intel a 26% higher boost clock. Shading units favor AMD at 320 versus 192, as do TMUs at 20 versus 12. Texture rate favors AMD at 20.60 GTexel/s against Intel's 15.60 GTexel/s, but pixel rate favors Intel at 10.40 GPixel/s versus 8.240 GPixel/s.

FP32 compute is higher on AMD at 659.2 GFLOPS compared to Intel's 499.2 GFLOPS, while Intel uniquely offers FP16 performance at 998.4 GFLOPS. Memory is the starkest split: AMD provides 2 GB of GDDR5 on a 64-bit bus with 36.00 GB/s bandwidth, while Intel uses system-shared memory with no dedicated capacity or fixed bandwidth. Process node differs at 14 nm+++ for Intel versus 28 nm for AMD, and transistor counts are only listed for AMD at 690 million with a die size of 56 mm². Bus interfaces differ as well: Intel uses Ring Bus, AMD uses PCIe 3.0 x8. TDP is listed only for Intel at 15 W; AMD's TDP is not provided. Display outputs are motherboard-dependent for Intel and portable-device-dependent for AMD.

Head-to-Head Benchmarks

The database records a single head-to-head benchmark between these two GPUs, the Geekbench OpenCL test. Intel UHD Graphics 730 scores 5988, and AMD Radeon R5 M435 scores 5859, yielding a 2.2% win for Intel. This result is consistent with Intel's position in its nearestRivals list, where its average score of 5929 sits within 0.9% of the NVIDIA Quadro K4000 (5982) and 0.7% of the AMD Radeon HD 8750M (5970). The Radeon R5 M435's average of 5859 places it 1.2% behind Intel and 1.6% behind both the HD 8730M and Quadro K620M, while sitting 0.3% ahead of the Radeon R7 M465.

The 2.2% delta in the head-to-head test is modest but notable given the hardware disparity. AMD's 320 shading units and 659.2 GFLOPS FP32 throughput should theoretically dominate compute-heavy OpenCL workloads, yet Intel's higher 1300 MHz boost clock and newer Generation 12.1 architecture close the gap and then some. Intel's pixel rate advantage of 10.40 GPixel/s versus 8.240 GPixel/s suggests better rasterization efficiency per clock, which can influence OpenCL kernels that involve image processing or framebuffer operations. Additionally, Intel's Vulkan 1.4 support and DirectX 12 (12_1) compliance indicate a more modern driver stack, which may extract better performance from the same workload than AMD's older GCN 1.0 with Vulkan 1.2.170.

In the broader context, both GPUs sit at the 33rd percentile of all GPUs, meaning they are entry-level parts. Intel's average score of 5929 is nearly identical to the AMD Radeon HD 8730M (5955, -0.4%) and NVIDIA Quadro K620M (5957, -0.5%), showing that the UHD 730 performs in line with older mid-range mobile parts. The Radeon R5 M435, with an average of 5859, trails the same rivals by 1.6%, but the delta to the R7 M465 (5841, 0.3%) shows it leads the immediate lower tier. The benchmark data does not include Vulkan results for the AMD part, while Intel shows a Geekbench Vulkan score of 5870, suggesting Intel has a measurable presence in that API that AMD lacks in this comparison.
