AMD Radeon 860M vs AMD Radeon RX 6450M Comparison

Where Each One Wins

The AMD Radeon 860M is an integrated graphics processor built on the RDNA 3.5 architecture, designed for portable devices where power efficiency is paramount. Its recorded benchmark data places it in the 72nd percentile among all GPUs in the database, with an average benchmark score of 26,401. The Radeon 860M has two recorded benchmark results: a Geekbench OpenCL score of 22,759 and a Geekbench Vulkan score of 30,043.

The AMD Radeon RX 6450M is a discrete mobile GPU based on the RDNA 2.0 architecture, drawing from the Radeon RX 6000 series. It sits in the 50th percentile among all GPUs, but has no recorded benchmark scores in the database. This absence of measurement data means the RX 6450M cannot be placed in direct head-to-head competition through the recorded results, though its architectural specifications allow for meaningful comparison.

The use-case split is largely defined by form factor and system integration. The 860M functions as an IGP with a 15 W TDP and system-shared memory, making it suitable for thin-and-light portable devices where dedicated graphics hardware is not feasible. The RX 6450M, with its 50 W TDP and 4 GB of dedicated GDDR6 memory, targets systems that can accommodate a discrete mobile GPU while maintaining a compact footprint. The RX 6450M uses a PCIe 4.0 x4 interface, while the 860M uses PCIe 4.0 x8.

For workloads that rely on the Vulkan API, the 860M delivers its strongest recorded performance, with the 30,043 Geekbench Vulkan score exceeding its OpenCL result by a substantial margin. The RX 6450M has no comparable recorded data, so its API-specific behavior cannot be quantified from the database.

Architecture Differences

The two GPUs represent different architectural generations from AMD. The Radeon 860M uses the RDNA 3.5 architecture on a 4 nm process node from TSMC, while the Radeon RX 6450M uses RDNA 2.0 on a 6 nm process node, also from TSMC. The 860M belongs to the Navi III IGP generation (Strix Point Mobile) and uses the Krackan Point chip. The RX 6450M belongs to the Navi Mobile generation (RX 6000M) and uses the Navi 24 chip.

The manufacturing process difference is significant: the 860M's 4 nm node is smaller than the RX 6450M's 6 nm node, which typically allows for higher transistor density and improved power efficiency. However, the RX 6450M has a known transistor count of 5,400 million on a 107 mm² die, yielding a transistor density of 50.5 million per mm². The 860M's transistor count and die size are listed as unknown in the database.

Compute resources differ notably between the two. The RX 6450M has 768 shading units, 48 texture mapping units, and 32 raster output units. The 860M has 512 shading units, 32 texture mapping units, and 16 raster output units. The RX 6450M also has 12 ray tracing cores compared to 8 on the 860M. Neither GPU has tensor cores listed.

Clock behavior differs substantially. The 860M has a base clock of 600 MHz and a boost clock of 3000 MHz, while the RX 6450M has a base clock of 2000 MHz, a boost clock of 2460 MHz, and a game clock of 2220 MHz. The 860M's much higher boost ceiling compensates for its lower base clock, but the sustained operating characteristics depend on thermal and power limits in the host system.

Memory architecture is fundamentally different. The 860M uses system-shared memory with system-dependent bandwidth, while the RX 6450M has 4 GB of dedicated GDDR6 memory on a 64-bit bus with 128.0 GB/s bandwidth and 16 Gbps effective memory speed.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon 860M and the AMD Radeon RX 6450M, and the win counts for both items are zero. The RX 6450M has no recorded benchmark scores at all, which prevents any direct numerical comparison of application performance.

The 860M's recorded scores provide context for its standing. Its Geekbench Vulkan score of 30,043 is notably higher than its Geekbench OpenCL score of 22,759, indicating that the Vulkan API path extracts more performance from the RDNA 3.5 architecture in the recorded tests. The average benchmark score of 26,401 places the 860M close to several rivals in the database.

The nearest rivals to the 860M include the NVIDIA GeForce MX550 with an average score of 26,421, a delta of -0.1 percent relative to the 860M. The NVIDIA GeForce RTX 5060 averages 26,331, which is 0.3 percent behind the 860M. The AMD Radeon RX 5700 XT 50th Anniversary scores 26,553 on average, 0.6 percent ahead of the 860M. The NVIDIA RTX A4000 averages 26,683, 1.1 percent ahead of the 860M. These deltas are all within roughly one percent, indicating that the 860M clusters tightly with these desktop and mobile parts in aggregate score.

Without recorded benchmarks for the RX 6450M, its performance relative to the 860M cannot be established from measured data. The specification differences suggest the RX 6450M has higher raw compute throughput on paper, but the database does not confirm this through benchmark results.
