A: Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Q: What is the benchmark situation for each GPU?

A: The RX 7700S has three recorded benchmark scores: 2185 in 3DMark Steel Nomad DX12, 62983 in Geekbench OpenCL, and 36380 in Geekbench Vulkan, giving it an average score of 33849 and a percentile rank of 78 among all GPUs. The Arc G3 has no recorded benchmark scores and an average score of 0, placing it at the 50th percentile.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon RX 7700S uses RDNA 3.0, a dedicated discrete mobile GPU architecture with a 6 nm process from TSMC. It packs 13,300 million transistors into a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter. The Intel Arc G3, in contrast, is built on Xe3-LPG, an integrated graphics architecture using a 3 nm process from Intel, and its transistor count and die size are not recorded in the database.

Compute resources differ substantially. The RX 7700S has 2048 shading units, 128 texture mapping units, 64 ROPs, and 32 ray tracing cores. The Arc G3 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. These numbers indicate the AMD part has roughly 60% more shading units, 3.2 times the TMUs, and 3.2 times the ROPs compared to the Intel part.

The memory systems are fundamentally different in design. The RX 7700S uses dedicated 8 GB GDDR6 memory on a 128-bit bus, with 288.0 GB/s of bandwidth and a memory clock of 2250 MHz (18 Gbps effective). The Arc G3 relies on system shared memory, with its bandwidth described as "System Dependent." This is a critical architectural distinction: one is a discrete solution with its own memory pool, while the other is an integrated GPU that shares system resources.

Clock behavior also differs. The RX 7700S has a base clock of 1500 MHz, a boost clock of 2500 MHz, and a game clock of 2200 MHz. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz, with no game clock listed. The AMD GPU operates at a much higher base frequency, while the Intel part has a lower base but a boost clock only 100 MHz below the AMD's boost.

The power envelopes reflect these architectural choices. The RX 7700S has a TDP of 100 W, while the Arc G3 has a TDP of 25 W. The bus interface also differs: the RX 7700S uses PCIe 4.0 x16, while the Arc G3 uses IGP, meaning it connects through the processor's internal fabric rather than a dedicated PCIe slot.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Radeon RX 7700S and the Intel Arc G3. The head-to-head benchmark array is empty, and both the win counters for item A and item B are zero. This means no direct performance measurements exist in the database that pit these two GPUs against each other in the same test.

However, the RX 7700S does have standalone benchmark scores that can be examined. In 3DMark Steel Nomad DX12, it scores 2185. In Geekbench OpenCL, it scores 62983. In Geekbench Vulkan, it scores 36380. These scores produce an average benchmark score of 33849, placing the GPU at the 78th percentile among all GPUs in the database.

The Arc G3 has no benchmark scores recorded at all. Its average benchmark score is listed as 0, and it sits at the 50th percentile. With no data points, there is no measured performance baseline for the Intel part to compare against the AMD part.

The nearest rivals for the RX 7700S provide context for its performance tier. The AMD Radeon HD 7950 has an average score of 33951, which is 0.3% higher than the RX 7700S. The AMD Radeon RX 480 scores 33997, 0.4% higher. The NVIDIA GeForce GTX 1060 5 GB scores 33694, which is 0.5% lower. The NVIDIA RTX A5000 scores 33622, 0.7% lower. These deltas are all within a narrow band, indicating the RX 7700S performs in a similar range to these older or differently positioned GPUs. The Arc G3 has no nearest rivals listed, so no comparable performance anchors exist for it.

Where Each One Wins

Based on the recorded data, the AMD Radeon RX 7700S holds the advantage in every measured performance category. Its shading unit count of 2048 versus 1280 means it has more parallel processing capacity. Its FP32 throughput of 20.48 TFLOPS is more than triple the Arc G3's 6.144 TFLOPS. The pixel rate of 160.0 GPixel/s versus 48.00 GPixel/s gives the RX 7700S a large lead in fill-rate-bound workloads. Texture rate follows the same pattern: 320.0 GTexel/s versus 96.00 GTexel/s.

Memory bandwidth is another decisive area. The RX 7700S has a dedicated 288.0 GB/s of bandwidth from its 8 GB GDDR6 pool, while the Arc G3's bandwidth is system dependent, meaning it shares whatever memory bandwidth the host platform provides. For workloads that stress memory throughput, the discrete solution has a structural advantage.

The Arc G3's wins are in efficiency and integration. Its TDP of 25 W is one quarter of the RX 7700S's 100 W, making it far more suited for low-power, thin-and-light designs. Its 3 nm process node is more advanced than the 6 nm node of the RX 7700S, which contributes to that lower power draw. The system shared memory approach eliminates the need for dedicated VRAM, which can reduce cost and complexity in an integrated design. The Arc G3's base clock of 300 MHz is far lower than the RX 7700S's 1500 MHz, allowing the Intel part to idle at very low power levels.

The RX 7700S wins on absolute performance, while the Arc G3 wins on power efficiency and system integration. The release dates reinforce this split: the RX 7700S launched in January 2023, while the Arc G3 is slated for May 2026, representing a much newer design generation.

The Verdict

The data shows two GPUs at opposite ends of the mobile graphics spectrum. The AMD Radeon RX 7700S is a discrete mobile GPU designed for performance. It delivers 20.48 TFLOPS FP32, 288.0 GB/s of dedicated memory bandwidth, and a 78th percentile ranking among all GPUs in the database. Its nearest rivals, including the GTX 1060 5 GB and RTX A5000, are within a 0.7% delta, placing it in a familiar performance tier for mid-range gaming laptops.

The Intel Arc G3 is an integrated GPU with a 25 W TDP, designed for efficiency and compact form factors. It has no recorded benchmark scores, so its real-world performance cannot be assessed from the database. Its 50th percentile ranking appears to be a default value rather than a measured result, given the zero average score.

For users who prioritize raw frame rates, compute throughput, and memory bandwidth, the RX 7700S is the clear choice from the recorded data. Its shading units, TMUs, ROPs, and ray tracing cores are all substantially higher. The 3.33 times higher FP32 throughput and 3.33 times higher pixel rate are decisive for any graphics workload that scales with these resources.

For users who prioritize battery life, thermal headroom, and system simplicity, the Arc G3 aligns better with those needs. Its 25 W TDP is a fraction of the RX 7700S's 100 W, and its system shared memory approach means no dedicated VRAM allocation is required. The 3 nm process also indicates a more modern manufacturing technique, which typically correlates with better power efficiency per unit of work.

The database contains no direct head-to-head benchmarks between these two GPUs, so any direct performance comparison must rely on the standalone scores and architectural specifications. The RX 7700S has measured results; the Arc G3 does not. Until benchmark data for the Arc G3 is recorded, the RX 7700S remains the only one of the two with verifiable performance in the database. The choice ultimately depends on whether the use case demands measured performance or minimal power consumption.
