AMD Radeon R7 M465

The AMD Radeon R7 M465 is a mobile discrete graphics processor built on the GCN 3.0 architecture, utilizing the Topaz chip produced on TSMC's 28 nm process. It carries 1,550 million transistors on a 125 mm² die, translating to a transistor density of 12.4 million per square millimeter. The GPU operates with a base clock of 730 MHz and a boost clock of 1024 MHz, delivering 786.4 GFLOPS of FP32 compute and an identical 786.4 GFLOPS for FP16, indicating a 1:1 ratio. Benchmark data shows a Geekbench OpenCL score of 5841, placing it in the 33rd percentile of all GPUs. The production status is end-of-life, with a release date of May 14, 2016, succeeding the Solar System family and preceding Polaris Mobile.

How It Compares

The closest rival, the AMD Radeon R5 M435, scores 5816, which is 0.4% lower than the R7 M465's 5841. This is a marginal difference, effectively placing the two GPUs in a statistical tie for raw compute performance. The data suggests that a user moving from one to the other would see no meaningful change in OpenCL workloads; the 25-point gap is well within normal run-to-run variance.

The Intel UHD Graphics P630, an integrated solution, achieves 5760, trailing the R7 M465 by 1.4%. While the gap is small in percentage terms, the fact that a discrete GPU barely edges out an integrated part highlights the R7 M465's modest absolute performance level. The data implies that for basic acceleration tasks, the distinction between this discrete chip and a modern iGPU is practically negligible.

The NVIDIA GeForce GTX 670MX posts a score of 5742, which is 1.7% behind the R7 M465. This older NVIDIA part is from a different architectural generation, yet the performance delta remains minimal. Benchmark results indicate that the R7 M465 holds a slight edge, but the comparison underscores that this AMD chip competes with GPU solutions from several years prior, not with contemporary offerings.

The AMD Radeon HD 8750M is the only rival that scores higher, with 5946, representing a 1.8% advantage over the R7 M465. This is notably the largest delta in the rival group, though still under two percent. The data reveals that the R7 M465 does not even lead its own predecessor family by a significant margin, suggesting it is a modest refresh rather than a generational leap in capability.

Power and Cooling

The FACT PACK does not specify a TDP (thermal design power) for the Radeon R7 M465, nor does it list a suggested PSU rating or power connector requirements. Without these figures, the analysis must rely on the chip's specifications to infer its thermal envelope. The 28 nm process node and the relatively low boost clock of 1024 MHz, combined with a 64-bit memory bus, point toward a design that prioritizes efficiency over raw throughput.

Given the absence of power connector data, it is reasonable to conclude that this GPU is designed to draw power exclusively from the motherboard slot, which in a mobile context means the system's dedicated power delivery is sufficient. The lack of a suggested PSU in the FACT PACK implies that the R7 M465 was intended for pre-built laptops where cooling and power are engineered as a complete system, not for end-user upgrades. The pixel rate of 8.192 GPixel/s and texture rate of 24.58 GTexel/s are modest figures, further reinforcing that thermal demands are likely low enough for standard mobile cooling solutions.

The memory operates at 1125 MHz with a 4.5 Gbps effective data rate, and the core's 384 shading units are spread across 24 texture mapping units and 8 render output units. These specifications collectively suggest that the GPU's power draw would be conservative, but without explicit TDP data, any numerical assertion would be speculative. The data available indicates a part that fits into thin-and-light laptops or budget notebooks, where cooling is adequate for lower-power discrete GPUs.

Who Should Consider It

Benchmark results show the R7 M465 scoring 5841 on Geekbench OpenCL, which lands it in the 33rd percentile of all GPUs. This percentile rank is telling: the majority of GPUs in the database outperform it. For gaming, this means the R7 M465 is suited for 720p resolution with low to medium settings in older titles, where the 786.4 GFLOPS of FP32 compute can keep frame rates playable.

At 1080p, the data implies significant compromises. The 36.00 GB/s of memory bandwidth and 8 ROPs are limiting factors for pixel-heavy workloads, so modern games would require the lowest settings and even then may struggle to maintain smooth performance. The 2 GB VRAM capacity is another constraint, as textures at 1080p can exceed this allocation, leading to stuttering or texture pop-in.

For non-gaming tasks, the R7 M465 is more viable. Its 1.4% lead over the Intel UHD Graphics P630 suggests it can handle basic video playback, office applications, and light photo editing without issue. Users who primarily need a discrete GPU for general acceleration rather than gaming would find it adequate, but those expecting a significant boost over integrated graphics should temper expectations based on the narrow delta over the Intel part.

The 4.5 Gbps effective memory speed, while modest, is still GDDR5, which offers better bandwidth than the DDR3/LPDDR3 often paired with integrated graphics. This gives the R7 M465 an edge in memory-sensitive tasks, but the overall compute ceiling remains low, as evidenced by its position in the 33rd percentile.

Ray Tracing and Feature Set

The Radeon R7 M465 has no dedicated ray tracing cores and no tensor cores, as these fields are null in the FACT PACK. This places it firmly in the pre-RTX era of GPU design, where ray tracing was not a hardware-accelerated feature. The architecture, GCN 3.0, predates AMD's ray tracing solutions, so any ray-traced effects would rely on compute shaders, which would be prohibitively slow given the 786.4 GFLOPS of FP32 performance.

The feature set is defined by its API support: DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170. This means the GPU can run modern games that require these APIs, but the feature level 12_0 is the baseline for DirectX 12, lacking advanced features like mesh shaders or variable rate shading found in later versions. The Vulkan 1.2.170 support does allow for lower-level access to the hardware, which can improve performance in well-optimized titles.

The absence of tensor cores means no accelerated AI features such as DLSS, and the lack of RT cores means no hardware-accelerated ray tracing. The GPU's FP16 performance is identical to FP32 at 786.4 GFLOPS, indicating no dedicated half-precision acceleration, which is common for this era of hardware. The bus interface is PCIe 3.0 x8, which provides sufficient bandwidth for the 36.00 GB/s memory throughput but limits data transfer rates compared to x16 slots.

Memory Subsystem

The R7 M465 is equipped with 2 GB of GDDR5 memory on a 64-bit bus, yielding a bandwidth of 36.00 GB/s. This is a significant bottleneck for the GPU, as the narrow bus width restricts data flow, particularly at higher resolutions. The memory clock runs at 1125 MHz, translating to a 4.5 Gbps effective data rate, which is standard for GDDR5 of that generation.

For 1080p gaming, the 2 GB capacity is borderline insufficient for modern titles with high-resolution textures. The 36.00 GB/s bandwidth further compounds this issue, as it limits the rate at which textures and geometry can be streamed to the GPU. At 720p, the memory subsystem is more manageable, and the GPU can rely on its 8 ROPs to handle pixel output at a rate of 8.192 GPixel/s.

The texture rate of 24.58 GTexel/s, derived from 24 TMUs at the boost clock, is also modest. In practice, this means the R7 M465 will struggle with games that demand high texture fill rates, such as open-world titles with dense environments. The 64-bit bus is the primary limitation, as it halves the bandwidth compared to a 128-bit bus at the same memory speed, making the GPU ill-suited for resolutions above 1080p.

Benchmark Performance

The Geekbench OpenCL score of 5841 places the R7 M465 in the 33rd percentile of all GPUs, indicating that two-thirds of GPUs in the database outperform it. Against its nearest rivals, the deltas are tight: it leads the R5 M435 by 0.4%, the Intel UHD Graphics P630 by 1.4%, and the GTX 670MX by 1.7%, while trailing the HD 8750M by 1.8%. These percentage differences are all under two percent, suggesting that the R7 M465 sits in a performance cluster where no clear winner exists among its immediate competitors.

The FP32 compute of 786.4 GFLOPS is the raw throughput figure that drives the OpenCL score. This is a modest number, and the benchmark data confirms that it translates to real-world performance that is only marginally better than integrated graphics like the Intel P630. The 1.4% lead over the P630 is within the margin of error for many benchmarks, meaning the R7 M465 does not offer a compelling discrete-GPU advantage for compute workloads.

The largest delta in the rival group is the 1.8% deficit to the HD 8750M. This is notable because the HD 8750M is an older part, yet it still outperforms the R7 M465. The data suggests the R7 M465 is not a significant step forward in performance, even relative to its direct predecessors. For users considering this GPU, the benchmark results indicate that it is a low-end solution suitable for basic acceleration, not for demanding gaming or compute tasks. The narrow deltas across all four rivals reinforce that the R7 M465 delivers performance that is largely interchangeable with its closest peers.
