AMD Radeon 8065S vs AMD Radeon RX 9070 Comparison

The Verdict

The database comparison between the AMD Radeon 8065S and the AMD Radeon RX 9070 shows two distinctly positioned products. The RX 9070 is a high-performance desktop-class graphics card, while the 8065S is a mobile integrated graphics processor. The RX 9070 holds the clear performance advantage across every recorded metric. Its average benchmark score of 23877 places it in the 69th percentile of all GPUs, while the 8065S has no recorded benchmark scores and sits in the 50th percentile. The RX 9070 offers roughly 2.35 times the FP32 compute throughput of the 8065S (36.13 TFLOPS versus 15.36 TFLOPS), more than double the pixel throughput (322.6 GPixel/s versus 192.0 GPixel/s), and a higher texture rate (564.5 GTexel/s versus 480.0 GTexel/s). The data indicates that the RX 9070 is the choice for users who need a discrete add-in card with substantial rendering power and a dedicated memory subsystem. The 8065S is for systems where a low-power integrated solution is acceptable, as it consumes 55 W compared to the RX 9070's 220 W and requires no power connectors or slot width, being an IGP. Users who need a desktop GPU with a dedicated 16 GB GDDR6 memory pool and a 256-bit bus should select the RX 9070. Users with portable or compact devices where a dedicated card is not feasible should rely on the 8065S.

Architecture Differences

The two GPUs come from different architectural generations and target different market segments. The AMD Radeon 8065S uses the Gorgon Halo chip with RDNA 3.5 architecture, belongs to the Navi Mobile (RX 8000M) generation, and is built on a 4 nm process at TSMC with a die size of 308 mm². The AMD Radeon RX 9070 uses the Navi 48 chip with RDNA 4.0 architecture, belongs to the Navi IV (RX 9000) generation, and is also built on a 4 nm TSMC process but with a larger die size of 357 mm². The RX 9070 contains 53,900 million transistors, while the transistor count for the 8065S is not recorded; the RX 9070 has a transistor density of 151.0M per mm².

The streaming processor counts differ significantly. The RX 9070 has 3584 shading units, 224 texture mapping units, 128 ROPs, and 56 ray tracing cores. The 8065S has 2560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores. The RX 9070's higher ROP count contributes to its pixel rate advantage, and its larger TMU count supports its higher texture throughput.

Clock behavior also differs. The 8065S operates with a base clock of 1295 MHz and a boost clock of 3000 MHz, while the RX 9070 has a base clock of 1330 MHz, a boost clock of 2520 MHz, and a game clock of 2070 MHz. The 8065S reaches a higher boost frequency, but the RX 9070's larger shader array and higher sustained game clock produce greater overall throughput. The 8065S uses system-shared memory, with type, bus width, and bandwidth all dependent on the host system. The RX 9070 uses 16 GB of GDDR6 memory on a 256-bit bus with 644.6 GB/s of bandwidth and a memory clock of 2518 MHz (20.1 Gbps effective).

Power delivery separates the two substantially. The 8065S has a 55 W TDP, no power connectors, and an integrated form factor. The RX 9070 has a 220 W TDP, requires two 8-pin power connectors, a 550 W suggested power supply, and occupies a dual-slot width. Both support PCIe 5.0 x16, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 9070 provides display outputs of one HDMI 2.1b and three DisplayPort 2.1a, while the 8065S's outputs are listed as portable device dependent. The RX 9070 has a launch MSRP of 549 USD.

Head-to-Head Benchmarks

The RX 9070 has a recorded set of benchmark results, while the 8065S has no entries in the database, which makes direct numeric comparison impossible for individual test scores. The RX 9070's average benchmark score of 23877 and its 69th percentile ranking among all GPUs indicate a solid mid-to-high tier position. Its nearest rivals in the database include the NVIDIA GeForce GTX TITAN Z with an average score of 23736 and a delta of 0.6 percent, the AMD Radeon RX 6800S with a score of 24063 and a delta of -0.8 percent, the NVIDIA GeForce RTX 3080 Mobile with a score of 23628 and a delta of 1.1 percent, and the NVIDIA GeForce RTX 2080 SUPER with a score of 24170 and a delta of -1.2 percent. These deltas show that the RX 9070 is within roughly one percent of these comparable products, neither clearly dominating nor being dominated by them.

In the RX 9070's individual tests, the highest recorded score is the Geekbench OpenCL result of 131539, followed by a Passmark G3D score of 25381 and a Passmark GPU Compute score of 14737. The Steel Nomad DX12 test produced a score of 6290, and the Geekbench Vulkan score was 58705. Passmark legacy tests show lower numbers: DirectX 10 at 141, DirectX 11 at 281, DirectX 12 at 74, and DirectX 9 at 343, with a G2D score of 1280.

The absence of benchmark records for the 8065S means the performance gap must be inferred from architectural specifications. The RX 9070's FP32 throughput of 36.13 TFLOPS versus the 8065S's 15.36 TFLOPS indicates a 2.35x advantage for the discrete card. The pixel rate of 322.6 GPixel/s for the RX 9070 outperforms the 8065S's 192.0 GPixel/s by a factor of 1.68, while the texture rate of 564.5 GTexel/s versus 480.0 GTexel/s shows a narrower but still significant 1.18x lead. The RX 9070's dedicated memory system with 644.6 GB/s bandwidth stands against the 8065S's system-dependent shared memory, which carries no fixed bandwidth figure.

Where Each One Wins

The RX 9070 wins in every category where the database records a measurable specification. It has more shading units (3584 versus 2560), more TMUs (224 versus 160), more ROPs (128 versus 64), and more ray tracing cores (56 versus 40). Its FP32 compute of 36.13 TFLOPS is more than double the 8065S's 15.36 TFLOPS, and its FP16 output matches its FP32 at a 1:1 ratio for both cards. The RX 9070's pixel rate of 322.6 GPixel/s and texture rate of 564.5 GTexel/s both exceed the 8065S's respective 192.0 GPixel/s and 480.0 GTexel/s. The RX 9070 also provides a dedicated memory subsystem with 16 GB of GDDR6, a 256-bit bus, and 644.6 GB/s bandwidth, whereas the 8065S depends entirely on shared system memory with no fixed bandwidth.

The 8065S wins in power efficiency and integration. Its 55 W TDP is one quarter of the RX 9070's 220 W TDP. It requires no power connectors, occupies no expansion slot as an IGP, and its display outputs are portable device dependent, meaning it is designed for integrated environments. Its boost clock of 3000 MHz is higher than the RX 9070's 2520 MHz boost, though this does not translate into higher overall throughput given the smaller shader array. The 8065S also has a smaller die size at 308 mm² versus 357 mm², which suggests a more compact implementation.

For users building or upgrading a desktop system with a discrete card, the RX 9070 is the clear performer. It delivers benchmark scores in the 69th percentile, places near the AMD Radeon RX 6800S and NVIDIA GeForce RTX 2080 SUPER within about one percent, and provides the memory bandwidth needed for high-resolution workloads. For users in the mobile or compact device segment, the 8065S offers a lower-power integrated alternative with modern API support and a high boost clock, but no recorded benchmark results to quantify its real-world standing. The data positions the RX 9070 as the performance-focused option and the 8065S as the power-conscious integrated solution.
