AMD Radeon RX 6450M vs Intel Arc Graphics 4 Xe Mobile Comparison

The Verdict

The recorded data places the AMD Radeon RX 6450M and the Intel Arc Graphics 4 Xe Mobile in the same percentile tier, both sitting at the 50th percentile versus all GPUs. This indicates that, within the database’s aggregate scoring, neither part establishes a dominant lead over the other in overall standing. The AMD Radeon RX 6450M is a discrete mobile GPU built on the RDNA 2.0 architecture, featuring a 6 nm process node and a 50 W power envelope. The Intel Arc Graphics 4 Xe Mobile is an integrated solution on Intel’s 3 nm process, using the Xe3-LPG architecture and consuming 25 W.

For users selecting between these two, the data suggests that the AMD part is positioned for tasks requiring higher raw throughput and dedicated memory. Its 4 GB of GDDR6 memory on a 64 bit bus delivers 128.0 GB/s of bandwidth, a fixed resource that does not depend on system configuration. The Intel part, by contrast, uses System Shared memory, with bandwidth listed as System Dependent, meaning its performance in memory-sensitive workloads will scale with the host platform’s memory configuration. The AMD RX 6450M also carries a higher compute ceiling, with 3.779 TFLOPS of FP32 performance versus 2.355 TFLOPS for the Intel Arc Graphics 4 Xe Mobile.

The Intel part, however, operates at a significantly lower power draw, 25 W versus 50 W. This makes it suitable for thin-and-light portable devices where power efficiency is prioritized over absolute performance. The AMD Radeon RX 6450M, with its higher TDP, is suited for larger laptops that can accommodate its thermal and power requirements. The data does not show a clear winner across the board; instead, the choice hinges on whether the user needs a fixed dedicated memory pool and higher compute rates, or a lower-power integrated solution with shared memory.

Architecture Differences

The AMD Radeon RX 6450M uses the Navi 24 chip, built on the RDNA 2.0 architecture, and is manufactured on a 6 nm process at TSMC. It contains 5,400 million transistors on a 107 mm² die, yielding a transistor density of 50.5 million transistors per square millimeter. The Intel Arc Graphics 4 Xe Mobile uses the Panther Lake chip, built on the Xe3-LPG architecture, and is manufactured on Intel’s 3 nm process. Its transistor count and die size are listed as unknown in the database.

The AMD part features 768 shading units, 48 texture mapping units, and 32 ROPs. It includes 12 ray tracing cores. The Intel part has 512 shading units, 32 TMUs, and 16 ROPs, with 4 ray tracing cores. These differences in execution resources directly contribute to the compute throughput gap: the AMD GPU delivers 3.779 TFLOPS of FP32 compute and 7.557 TFLOPS of FP16 (2:1 ratio), while the Intel GPU delivers 2.355 TFLOPS of FP32 and 4.710 TFLOPS of FP16.

Clock behavior also differs. The AMD Radeon RX 6450M has a base clock of 2000 MHz, a game clock of 2220 MHz, and a boost clock of 2460 MHz. The Intel Arc Graphics 4 Xe Mobile has a base clock of 300 MHz and a boost clock of 2300 MHz, with no game clock listed. The AMD part’s memory runs at 2000 MHz with 16 Gbps effective data rate, while the Intel part’s memory is System Shared with no dedicated clock or bus width specified.

Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity is present. The AMD Radeon RX 6450M uses a PCIe 4.0 x4 bus interface, while the Intel Arc Graphics 4 Xe Mobile uses an IGP bus interface. The AMD part is listed as having no power connectors and a slot width of IGP, meaning it is designed for mobile integration despite being a discrete-class chip. The Intel part likewise has no power connectors and an IGP slot width.

The pixel rate for the AMD part is 78.72 GPixel/s, and the texture rate is 118.1 GTexel/s. The Intel part’s pixel rate is 36.80 GPixel/s, and its texture rate is 73.60 GTexel/s. These figures represent the theoretical fill-rate capacity of each GPU, and the AMD part leads in both measures by a substantial margin.

Where Each One Wins

The AMD Radeon RX 6450M wins on raw compute and fixed-memory bandwidth. Its FP32 throughput of 3.779 TFLOPS is 60% higher than the Intel part’s 2.355 TFLOPS. The FP16 rate of 7.557 TFLOPS versus 4.710 TFLOPS represents a similar gap. For workloads that scale with shader count and clock speed, such as general 3D rendering or compute tasks, the AMD part holds a clear advantage.

The AMD part also wins on memory determinism. With 4 GB of GDDR6 memory and 128.0 GB/s of dedicated bandwidth, its performance does not depend on the host system’s memory configuration. The Intel part’s System Shared memory and System Dependent bandwidth mean that its effective memory performance can vary widely based on the laptop’s RAM speed, channel configuration, and whether the system is using dual-channel memory.

The Intel Arc Graphics 4 Xe Mobile wins on power efficiency. Its 25 W TDP is exactly half of the AMD part’s 50 W TDP. This makes it a better fit for compact laptops where thermal dissipation is limited and battery life is a priority. The Intel part’s 300 MHz base clock also suggests a very low idle or light-load power state, which can benefit always-on portable devices.

The Intel part also holds a process node advantage, using Intel’s 3 nm process versus AMD’s 6 nm process at TSMC. While the database does not provide transistor counts for the Intel chip, the smaller process node allows the Intel GPU to achieve its 25 W power envelope while still delivering 2.355 TFLOPS of FP32 compute.

In terms of release timing, the AMD Radeon RX 6450M launched on January 3, 2023, while the Intel Arc Graphics 4 Xe Mobile launched on January 26, 2026. The Intel part is part of the newer Arc Graphics-M generation for Panther Lake, while the AMD part belongs to the Navi Mobile generation within the RX 6000M series.

Head-to-Head Benchmarks

The database lists no direct benchmark scores for either GPU, and the head-to-head benchmark array is empty. Both parts have an average benchmark score of 0 and an equal percentile rank of 50 versus all GPUs. This means the recorded data does not provide individual workload results to compare. The analysis below is based entirely on the architectural and specification data recorded in the database.

The largest win for the AMD Radeon RX 6450M is in FP32 compute throughput. The AMD part’s 3.779 TFLOPS is 1.424 TFLOPS higher than the Intel part’s 2.355 TFLOPS, which is a 60.5% advantage. This is the single largest gap between the two parts in any measured specification.

The second-largest win for the AMD part is in pixel fill rate. The AMD GPU achieves 78.72 GPixel/s, while the Intel GPU achieves 36.80 GPixel/s. The AMD part is 41.92 GPixel/s ahead, which is a 113.9% advantage. This indicates that the AMD part can fill the screen with rendered pixels at more than double the rate of the Intel part.

The texture fill rate also favors the AMD part. The AMD Radeon RX 6450M delivers 118.1 GTexel/s, while the Intel Arc Graphics 4 Xe Mobile delivers 73.60 GTexel/s. The AMD part is 44.5 GTexel/s ahead, a 60.5% advantage that mirrors the FP32 ratio, which is expected given that texture rate scales with shader count and clock speed.

Memory bandwidth is another clear win for the AMD part. The AMD GPU has 128.0 GB/s of fixed GDDR6 bandwidth, while the Intel GPU has System Dependent bandwidth with no fixed figure recorded. In a best-case host configuration, the Intel part’s shared memory could approach or exceed that number, but the database records no fixed bandwidth for the Intel GPU, so the AMD part’s bandwidth is the only deterministic value available.

The Intel Arc Graphics 4 Xe Mobile wins on power consumption. Its 25 W TDP is 25 W lower than the AMD part’s 50 W TDP, a 50% reduction. This is the largest win for the Intel part in any recorded specification.

The Intel part also wins on process node size. Its 3 nm process is smaller than the AMD part’s 6 nm process, though the database does not record transistor counts for the Intel chip, so the density comparison cannot be made.

Ray tracing core count favors the AMD part. The AMD GPU has 12 ray tracing cores, while the Intel GPU has 4, a 3x difference. Both parts support DirectX 12 Ultimate, so ray tracing workloads are available on both, but the AMD part has more hardware resources dedicated to this task.

Clock speeds show a mixed picture. The AMD part has a higher base clock at 2000 MHz versus 300 MHz, and a higher boost clock at 2460 MHz versus 2300 MHz. The AMD part also has a recorded game clock of 2220 MHz, while the Intel part has no game clock listed. The Intel part’s low 300 MHz base clock suggests it can drop to a very low power state, which supports its 25 W TDP classification.

The release dates place the AMD part earlier, with a January 3, 2023 launch, while the Intel part launched on January 26, 2026. The AMD part’s predecessor is listed as Polaris Mobile, while the Intel part has no recorded predecessor. Neither part has a recorded successor.

The overall picture from the recorded data is that the AMD Radeon RX 6450M leads in compute throughput, fill rates, memory bandwidth, and ray tracing resources, while the Intel Arc Graphics 4 Xe Mobile leads in power efficiency and process node size. The equal percentile rank of 50 for both parts suggests that the database’s aggregate scoring places them in the same performance tier, despite the specification gaps.
