AMD Radeon 8065S vs AMD Radeon RX 9070 XT Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Radeon 8065S contains no benchmark entries, while the AMD Radeon RX 9070 XT has ten recorded tests. This makes a direct score-by-score comparison impossible. The RX 9070 XT delivers a 3DMark Steel Nomad DX12 score of 7,260, a Geekbench OpenCL score of 17,428, and a Geekbench Vulkan score of 65,879. Its Passmark results include a G3D score of 26,795 and a GPU Compute score of 15,864. The 8065S, by contrast, has no measured scores in the database, so its performance must be inferred from its architecture and specifications rather than direct head-to-head results.

The RX 9070 XT posts an average benchmark score of 13,543 across its tests. Its nearest rivals in the database include the AMD Radeon HD 7770M with an average score of 13,536, which places the RX 9070 XT just 0.1% ahead. The NVIDIA GeForce GTX 570 scores 13,515, a 0.2% gap, and the NVIDIA P106-090 scores 13,470, a 0.5% gap. The AMD Radeon Pro 555 trails at 13,407, putting the RX 9070 XT 1% ahead. These margins are narrow, suggesting the RX 9070 XT sits at the same performance tier as those older or lower-end parts in aggregate benchmarks, despite having a significantly different feature set.

The RX 9070 XT reaches 48.66 TFLOPS of FP32 throughput, while the 8065S reaches 15.36 TFLOPS. That is a 3.17x advantage for the RX 9070 XT in raw shader math. Texture rate follows a similar pattern: the RX 9070 XT delivers 760.3 GTexel/s versus 480.0 GTexel/s for the 8065S, a 1.58x lead. Pixel rate favors the RX 9070 XT even more decisively, with 380.2 GPixel/s against 192.0 GPixel/s, a 1.98x gap. These are the largest measurable deltas in the comparison, and they all point in one direction.

Clock behavior differs in an interesting way. The 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz, which is actually 30 MHz higher than the RX 9070 XT's 2970 MHz boost. The RX 9070 XT compensates with a much higher base clock of 1660 MHz and a game clock of 2400 MHz. The 8065S boost clock exceeding the RX 9070 XT boost clock by 1% is the only specification where the mobile part leads. The RX 9070 XT also has a dedicated memory clock of 2518 MHz (20.1 Gbps effective), whereas the 8065S relies on system shared memory with no dedicated clock.

Where Each One Wins

The RX 9070 XT wins every category where measured data exists. Its 16 GB of GDDR6 memory on a 256-bit bus delivers 644.6 GB/s of bandwidth. The 8065S uses system shared memory with bandwidth listed as system dependent, so no fixed figure can be compared. The RX 9070 XT also has 4,096 shading units, 256 texture mapping units, 128 ROPs, and 64 ray tracing cores. The 8065S has 2,560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores. Each of those counts is exactly double or close to double in the RX 9070 XT's favor.

For use cases that stress raw throughput, such as high-resolution gaming or compute workloads, the RX 9070 XT is the clear choice based on its 3.17x FP32 advantage and 1.98x pixel rate lead. For workloads that depend on memory bandwidth, the RX 9070 XT's 644.6 GB/s dedicated GDDR6 bandwidth far exceeds anything the 8065S can offer, since its bandwidth is system dependent and shared with the CPU. The 8065S does hold one genuine advantage: power consumption. Its TDP is 55 W, while the RX 9070 XT consumes 304 W, a 5.5x difference. This makes the 8065S suitable for environments where power draw is constrained, such as thin-and-light portable devices, while the RX 9070 XT demands a 700 W suggested PSU and dual 8-pin power connectors.

The 8065S also wins on physical footprint. It is an integrated graphics processor (IGP) with no power connectors and a slot width listed as IGP, whereas the RX 9070 XT is a dual-slot card with 2x 8-pin power connectors. The 8065S can fit into devices where no discrete card slot exists. Its display outputs are listed as portable device dependent, meaning the host system determines connectivity, while the RX 9070 XT provides 1x HDMI 2.1b and 3x DisplayPort 2.1a outputs.

Architecture Differences

The two GPUs come from different RDNA generations. The 8065S uses RDNA 3.5 with the Gorgon Halo chip, while the RX 9070 XT uses RDNA 4.0 with the Navi 48 chip. Both are built on TSMC's 4 nm process, so the manufacturing node is identical. The die sizes differ: the 8065S measures 308 mm², and the RX 9070 XT measures 357 mm². That is a 15.9% larger die for the RX 9070 XT. Transistor counts are not reported for the 8065S, but the RX 9070 XT contains 53,900 million transistors with a density of 151.0M per mm². The lack of transistor data for the 8065S prevents a direct density comparison, but the die size difference alone suggests the RX 9070 XT packs significantly more hardware.

The 8065S belongs to the Navi Mobile (RX 8000M) generation, while the RX 9070 XT belongs to the Navi IV (RX 9000) generation. Their predecessors also differ: the 8065S follows Polaris Mobile, and the RX 9070 XT follows Navi III. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. Both use a PCIe 5.0 x16 bus interface. The RX 9070 XT was released on 2025-03-05, while the 8065S has a release date of 2025-12-31, roughly ten months later. Both are listed as Active in production status.

Memory architecture is the most fundamental split. The 8065S has no dedicated VRAM; it shares system memory, with size, type, and bus width all listed as system shared. The RX 9070 XT has 16 GB of GDDR6 on a 256-bit bus. This affects not only bandwidth but also capacity, latency, and how memory pressure from other system components can impact GPU performance. The RX 9070 XT's dedicated memory pool isolates GPU workloads from CPU memory contention.

Power delivery also differs sharply. The 8065S draws 55 W and needs no external power connectors. The RX 9070 XT draws 304 W and requires 2x 8-pin connectors plus a 700 W suggested PSU. The 8065S's slot width is IGP, meaning it is integrated into the host processor package, while the RX 9070 XT is a dual-slot discrete card. These architectural choices target entirely different device classes.

The Verdict

The data shows two GPUs with the same manufacturer and process node but fundamentally different purposes. The RX 9070 XT dominates every measured performance metric. Its FP32 throughput of 48.66 TFLOPS versus 15.36 TFLOPS gives it a 3.17x lead. Its pixel rate of 380.2 GPixel/s versus 192.0 GPixel/s gives it a 1.98x lead. Its texture rate of 760.3 GTexel/s versus 480.0 GTexel/s gives it a 1.58x lead. It has 60% more shading units, 60% more TMUs, 100% more ROPs, and 60% more ray tracing cores than the 8065S. Its 644.6 GB/s of dedicated memory bandwidth is not a figure the 8065S can match, since that part's bandwidth is system dependent.

The 8065S wins on integration and power. Its 55 W TDP is 5.5x lower than the RX 9070 XT's 304 W. It requires no power connectors, no cooling beyond what the host device provides, and fits into a mobile form factor. The RX 9070 XT needs a 700 W PSU and dual-slot cooling. The 8065S also has a 30 MHz higher boost clock (3000 MHz versus 2970 MHz), though the RX 9070 XT's game clock of 2400 MHz and base clock of 1660 MHz suggest it sustains higher clocks under load.

The RX 9070 XT carries a launch MSRP of 599 USD. Its percentile rank among all GPUs is 55, versus 50 for the 8065S. Its average benchmark score of 13,543 places it 0.1% ahead of the AMD Radeon HD 7770M and 1% ahead of the AMD Radeon Pro 555. The 8065S has no recorded benchmarks, so its percentile rank of 50 is not supported by measured data.

For users who need maximum graphics performance in a desktop system with adequate power delivery, the RX 9070 XT is the only choice with recorded evidence. For users who need a GPU integrated into a low-power mobile device, the 8065S is the only option that fits, but no benchmark data exists to validate its performance claims. The database shows a clear performance hierarchy, but the absence of 8065S scores leaves a gap in the quantitative picture.
