AMD Radeon RX 7700S vs Intel Arc B770 Comparison

Where Each One Wins

The recorded data presents an unusual comparison: the AMD Radeon RX 7700S has a full set of benchmark results, while the Intel Arc B770 has no recorded benchmark scores in the database. The RX 7700S posts an average benchmark score of 33,849 across three tests, with a percentile ranking of 78 among all GPUs. The Arc B770, by contrast, carries a percentile ranking of 50 and an average benchmark score of 0, meaning the database contains no performance measurements for it.

Looking at the AMD card's individual results, the 3DMark Steel Nomad DX12 test returns a score of 2,185. The Geekbench OpenCL score reaches 62,983, while the Vulkan test yields 36,380. These numbers place the RX 7700S in a competitive position against its nearest rivals. The AMD Radeon HD 7950 averages 33,951, a delta of -0.3% relative to the RX 7700S. The AMD Radeon RX 480 averages 33,997, a -0.4% delta. The NVIDIA GeForce GTX 1060 5 GB averages 33,694, a +0.5% delta, and the NVIDIA RTX A5000 averages 33,622, a +0.7% delta. In practice, the RX 7700S sits within a single percentage point of all four rivals, indicating near-parity in aggregate performance.

For the Arc B770, the absence of benchmark data means no wins can be attributed to it. Every comparative statement must rely on architectural specifications rather than measured results. The RX 7700S therefore wins every recorded head-to-head category by default, simply because it has data and the Arc B770 does not.

Architecture Differences

The two GPUs diverge substantially in their underlying designs. The AMD Radeon RX 7700S uses the Navi 33 chip built on RDNA 3.0 architecture, codenamed Hotpink Bonefish, and belongs to the Navi Mobile generation under the RX 7000M series. It is fabricated on a 6 nm process at TSMC, with 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per mm². The Intel Arc B770 uses the BMG-G31 chip based on Xe2-HPG architecture, from the Battlemage generation in the Arc 7 series. It is built on a 5 nm process, also at TSMC, with a die size of 368 mm². The transistor count for the Intel chip is listed as unknown, and no density figure is recorded.

Clock speeds differ notably. The RX 7700S runs a base clock of 1500 MHz, a boost clock of 2500 MHz, and a game clock of 2200 MHz. The Arc B770 has a base clock of 2100 MHz and a boost clock of 2400 MHz, with no game clock specified. Memory clocks also vary: the AMD card operates at 2250 MHz with 18 Gbps effective speed, while the Intel card runs at 2000 MHz with 16 Gbps effective speed.

Memory configuration heavily favors the Intel part. The RX 7700S has 8 GB of GDDR6 on a 128-bit bus, delivering 288.0 GB/s of bandwidth. The Arc B770 has 16 GB of GDDR6 on a 256-bit bus, delivering 512.0 GB/s. That is a 224 GB/s bandwidth advantage and double the capacity for the Intel card. The AMD card's smaller memory footprint likely reflects its mobile-oriented design, while the Intel card's larger frame buffer targets desktop use.

Compute resources also differ. The RX 7700S contains 2048 shading units, 128 texture mapping units, 64 raster operation units, and 32 ray tracing cores. The Arc B770 doubles most of these: 4096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. Pixel rate for the AMD card is 160.0 GPixel/s, while the Intel card reaches 307.2 GPixel/s. Texture rate is 320.0 GTexel/s versus 614.4 GTexel/s. Interestingly, the FP32 performance is close: 20.48 TFLOPS for AMD versus 19.66 TFLOPS for Intel. FP16 performance shows 40.96 TFLOPS for AMD and 39.32 TFLOPS for Intel, both at a 2:1 ratio.

Power and physical specifications reveal different design targets. The RX 7700S has a TDP of 100 W, is an integrated graphics package (IGP) with no power connectors, and is described as portable device dependent for display outputs. The Arc B770 draws 225 W, uses a dual-slot form factor, requires a 6-pin plus 8-pin power connector, suggests a 550 W power supply, and offers 1x HDMI 2.1a plus 3x DisplayPort 2.1 outputs. Both use PCIe 4.0 x16 interfaces. The AMD card is active in production and released on 2023-01-03; the Intel card has a release date of 2025-12-31 with no production status listed. The AMD card's predecessor is Polaris Mobile, while the Intel card's predecessor is Alchemist.

The Verdict

The data supports a straightforward conclusion. The AMD Radeon RX 7700S is a measured, verified product with an average benchmark score of 33,849 and a 78th percentile ranking. The Intel Arc B770 has no recorded benchmarks, an average score of zero, and a 50th percentile ranking that appears provisional at best. For anyone relying on the database, the RX 7700S is the only option with performance evidence.

Architecturally, the Arc B770 offers superior raw specifications in memory capacity, bandwidth, pixel rate, and texture rate. It also doubles the shading units, TMUs, and ROPs. Yet those specifications carry no measured weight in this database. The FP32 throughput of the Intel card is actually slightly lower than the AMD card, at 19.66 TFLOPS versus 20.48 TFLOPS. The power envelope is also much larger, at 225 W versus 100 W.

For users who prioritize verified benchmark results, the RX 7700S is the clear choice. For users who prioritize theoretical specifications on paper, the Arc B770 appears more capable in several areas, but those capabilities are unconfirmed by any test data. The verdict from the database is unambiguous: the AMD part wins because it has data; the Intel part cannot claim victory without measurements.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, listing zero wins for each GPU. This means no direct comparison tests exist between the AMD Radeon RX 7700S and the Intel Arc B770. The only benchmark data available belongs to the AMD card.

The RX 7700S delivers a 3DMark Steel Nomad DX12 score of 2,185. In Geekbench OpenCL, it scores 62,983, and in Geekbench Vulkan, it scores 36,380. These three results combine to produce the average of 33,849. The Intel Arc B770 contributes no scores to any of these tests.

When examining the relative performance of the AMD card, the closest rival is the NVIDIA RTX A5000, which trails by 0.7%. The NVIDIA GeForce GTX 1060 5 GB trails by 0.5%. On the other side, the AMD Radeon HD 7950 leads by 0.3%, and the AMD Radeon RX 480 leads by 0.4%. These deltas are small enough to be considered noise, indicating the RX 7700S performs essentially on par with these older or workstation-class GPUs.

The architectural comparison shows that the Intel Arc B770 should, in theory, outperform the AMD card in memory-bound scenarios. With 512.0 GB/s of bandwidth and 16 GB of capacity, the Intel card has a decisive advantage in texture-heavy workloads or large data sets. The pixel rate of 307.2 GPixel/s and texture rate of 614.4 GTexel/s also suggest higher fill rates. However, the FP32 compute throughput is nearly identical, with the AMD card slightly ahead at 20.48 TFLOPS versus 19.66 TFLOPS.

The power efficiency picture favors the AMD card. At 100 W, the RX 7700S delivers 20.48 TFLOPS of FP32 performance, while the Arc B770 requires 225 W for 19.66 TFLOPS. The AMD card achieves a higher compute density per watt, though the Intel card compensates with more memory and higher fill rates.

Without any measured benchmark results for the Arc B770, the database cannot confirm whether its architectural advantages translate into real-world performance. The RX 7700S stands as the only GPU in this comparison with verified scores, and those scores place it in the 78th percentile of all GPUs. The Arc B770's 50th percentile ranking appears to be a placeholder rather than a measured outcome.

The final analysis from the recorded data is that the AMD Radeon RX 7700S wins on the basis of having actual performance measurements, while the Intel Arc B770 remains an unverified specification sheet.
