AMD Radeon RX 7600S vs Intel Arc G3 Comparison

Where Each One Wins

The recorded data presents an asymmetric comparison. The AMD Radeon RX 7600S has a full benchmark suite with ten recorded scores, while the Intel Arc G3 has no recorded benchmark entries in the database. This means every measured performance win belongs to the RX 7600S by default, but the interesting question is what the Arc G3 can claim based on its architecture and specifications.

The RX 7600S establishes itself as a discrete-class mobile GPU. Its PassMark G3D score of 15,408 places it in the 60th percentile of all GPUs tracked by the database. Its average benchmark score of 16,696 puts it just 0.6% behind the NVIDIA T400 4 GB (16,792) and 1.1% ahead of the NVIDIA T400 (16,508). These are tight margins, indicating the RX 7600S sits in a crowded performance band where small architectural differences determine placement.

The Intel Arc G3, by contrast, has no scores to analyze. Its 50th percentile rating appears to be a default or estimated position rather than a measured result. The GPU relies on system shared memory, meaning its performance is dependent on the host platform's memory configuration. This is a fundamental difference: the RX 7600S has dedicated GDDR6 memory with fixed bandwidth, while the Arc G3's memory performance is variable.

For use-case segmentation, the RX 7600S wins every measurable category. Its PassMark DirectX 11 score of 140 versus its DirectX 12 score of 65 suggests it performs better under legacy DirectX 11 workloads. The DirectX 9 score of 211 is the highest among its legacy API results. Its OpenCL score of 68,012 in Geekbench indicates strong compute capability, and the Vulkan score of 73,868 is even higher, suggesting the architecture favors Vulkan's lower-level access.

The Arc G3's use case is defined by efficiency rather than raw performance. At 25 W TDP versus the RX 7600S's 75 W, it draws one-third the power. This places it in a different class of mobile devices, likely ultrathin laptops where battery life takes priority over frame rates. The data cannot confirm this directly, but the power envelope strongly implies it.

Architecture Differences

The two GPUs come from different manufacturers, process nodes, and architectural generations. The RX 7600S uses AMD's RDNA 3.0 architecture on a 6 nm TSMC process. It is built on the Navi 33 chip with the codename Hotpink Bonefish, belonging to the Navi Mobile (RX 7000M) generation. The Arc G3 uses Intel's Xe3-LPG architecture on a 3 nm Intel process, built on the Panther Lake chip and belonging to the Arc Graphics-M (Panther Lake) generation.

The transistor counts tell a story of design philosophy. The RX 7600S packs 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The Arc G3's transistor count and die size are listed as unknown, so no direct density comparison is possible. The process node difference, 6 nm versus 3 nm, suggests the Intel part can achieve higher density, but the database does not provide the numbers to confirm this.

The memory subsystems are fundamentally different. The RX 7600S has 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The Arc G3 uses system shared memory, meaning its bandwidth is system dependent. This is a critical architectural distinction: the RX 7600S has predictable, dedicated memory performance, while the Arc G3's memory performance varies with the host system's memory configuration.

Core counts show the RX 7600S has substantially more compute resources. It has 1,792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. The Arc G3 has 1,280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The RX 7600S has 40% more shading units and nearly three times the TMUs and ROPs. The ray tracing core disparity is even larger, with the RX 7600S having 2.8 times the Arc G3's count.

Clock behavior differs significantly. The RX 7600S has a 1,500 MHz base clock, a 2,200 MHz boost clock, and a 1,865 MHz game clock. The Arc G3 has a 300 MHz base clock and a 2,400 MHz boost clock. The Arc G3's base clock is dramatically lower, but its boost clock is 200 MHz higher than the RX 7600S. This suggests the Intel part is designed for aggressive boost behavior with very low idle states, consistent with its 25 W power target.

The compute throughput numbers reflect the core and clock differences. The RX 7600S delivers 15.77 TFLOPS FP32 and 31.54 TFLOPS FP16 (2:1). The Arc G3 delivers 6.144 TFLOPS FP32 and 12.29 TFLOPS FP16 (2:1). The RX 7600S has 2.57 times the FP32 throughput of the Arc G3.

Both GPUs share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are classified as IGP slot width with no power connectors and portable device dependent display outputs. Both have active production status.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two GPUs. The head-to-head array is empty, and both win counters are zero. However, the RX 7600S has its own benchmark suite that provides context for its performance level.

In 3DMark Steel Nomad DX12, the RX 7600S scores 1,888. This is its only 3DMark entry, and it demonstrates the GPU can handle modern DirectX 12 workloads at a modest level. The Geekbench results show OpenCL at 68,012 and Vulkan at 73,868. The Vulkan score being 8.6% higher than the OpenCL score suggests the RDNA 3.0 architecture responds well to Vulkan's lower overhead.

The PassMark suite reveals interesting API-level behavior. The DirectX 9 score of 211 is the highest legacy API result. DirectX 11 scores 140, DirectX 10 scores 74, and DirectX 12 scores 65. The DirectX 12 score being lower than DirectX 11 and DirectX 9 could indicate driver optimization priorities or architectural characteristics of the Navi 33 chip. The PassMark G2D score of 776 and G3D score of 15,408 show the GPU's 2D performance is strong relative to its 3D capability.

The GPU compute score of 6,520 in PassMark, combined with the Geekbench OpenCL result, confirms the RX 7600S has substantial compute throughput beyond graphics. Its FP32 rate of 15.77 TFLOPS places it in a range where it can handle light compute workloads, though the database does not include dedicated AI or ray tracing benchmarks.

The nearest rival data provides the most meaningful comparison points. The RX 7600S's average score of 16,696 is 0.6% behind the NVIDIA T400 4 GB (16,792) and 1.4% behind the NVIDIA Tesla M4 (16,932). It is 1.1% ahead of the NVIDIA T400 (16,508) and 1.2% ahead of the NVIDIA GeForce RTX 5090 D V2 (16,504). These margins are all within 1.4%, indicating the RX 7600S performs in a tightly clustered band around the 16,500 to 17,000 average score range.

The Verdict

The data supports a clear performance hierarchy, but the comparison is constrained by the Arc G3's empty benchmark record. For any workload measured by the database, the RX 7600S is the only option with verified results. Its 15.77 TFLOPS FP32 throughput, 256.0 GB/s dedicated memory bandwidth, and 28 ray tracing cores give it a substantial hardware advantage over the Arc G3's 6.144 TFLOPS, system shared memory, and 10 ray tracing cores.

The RX 7600S is the choice for applications that need predictable, dedicated graphics performance. Its 8 GB GDDR6 memory ensures consistent bandwidth regardless of the host system. Its 60th percentile ranking and tight competition with the NVIDIA T400 family show it performs in the lower-mid range of the GPU market. Users running DirectX 11 or DirectX 9 workloads may see better results than DirectX 12 based on the PassMark scores, but the GPU supports all modern APIs.

The Arc G3 is the choice for ultra-efficient mobile platforms. Its 25 W TDP is exactly one-third of the RX 7600S's 75 W TDP, and its 300 MHz base clock suggests aggressive power gating. The 2,400 MHz boost clock shows it can reach high frequencies when needed, but the 6.144 TFLOPS ceiling limits its sustained performance. Its system shared memory means real-world performance depends entirely on the host laptop's memory configuration.

The release dates reinforce the generational gap. The RX 7600S launched on 2023-01-03, while the Arc G3 is dated 2026-05-31. The Arc G3 belongs to a newer generation on a newer process node, but the database shows no measured evidence of its performance. Its 50th percentile rating appears unverified.

Neither GPU has a launch MSRP listed, so no pricing analysis is possible. The production status for both is active, meaning both are currently available in the market. The RX 7600S is the only one of the two with any benchmark evidence, and every measured metric favors it.
