AMD Radeon RX 9070 XT vs AMD Radeon RX Vega 11 Comparison

# AMD Radeon RX Vega 11 vs AMD Radeon RX 9070 XT

The AMD Radeon RX Vega 11 is an integrated graphics processor from the Picasso generation, built on a 12 nm process at GlobalFoundries, while the AMD Radeon RX 9070 XT is a discrete add-in board from the Radeon RX 9000 series, fabricated on TSMC's 4 nm node. The data shows a generational chasm: the RX 9070 XT wins both head-to-head benchmark comparisons, with a 28.1% lead in Geekbench OpenCL and a 79.4% lead in Geekbench Vulkan. However, the picture is more nuanced than raw scores suggest, as the RX Vega 11 holds a 56th percentile ranking versus the RX 9070 XT's 55th percentile among all GPUs, and their average benchmark scores (14385 vs 13543) actually favor the older integrated part. This oddity stems from different benchmark suites being used for each product, so direct comparisons require careful reading of the data.

FAQ

Q: Which GPU wins in Geekbench OpenCL?

A: The AMD Radeon RX 9070 XT scores 17428 versus the RX Vega 11's 12525, a 28.1% advantage for the newer card.

Q: How large is the Vulkan performance gap?

Q: Which card has a higher pixel fill rate?

A: The RX 9070 XT delivers 380.2 GPixel/s, compared to the RX Vega 11's 11.20 GPixel/s — a 34-fold difference.

Q: Are both GPUs still in production?

A: No. The RX Vega 11 is end-of-life, released in July 2019, while the RX 9070 XT is active, released in March 2025.

Architecture Differences

The architectural divide between these two AMD parts is substantial. The RX Vega 11 uses the GCN 5.0 architecture on a 12 nm process from GlobalFoundries, packing 4,940 million transistors into a 210 mm² die. The RX 9070 XT moves to RDNA 4.0 on TSMC's 4 nm node, with 53,900 million transistors in a 357 mm² die. Transistor density tells the story: the RX 9070 XT achieves 151.0M transistors per mm² versus 23.5M for the RX Vega 11, a 6.4-fold improvement in packing efficiency.

Compute resources differ dramatically. The RX Vega 11 has 704 shading units, 44 texture mapping units, and 8 ROPs. The RX 9070 XT has 4096 shading units, 256 TMUs, and 128 ROPs. The newer card also adds 64 ray tracing cores, which the RX Vega 11 completely lacks. Clock speeds are not comparable directly: the RX Vega 11 runs at a 300 MHz base and 1400 MHz boost, while the RX 9070 XT operates at 1660 MHz base, 2400 MHz game clock, and 2970 MHz boost. The FP32 throughput tells the real story — 1.971 TFLOPS for the RX Vega 11 versus 48.66 TFLOPS for the RX 9070 XT, a 24.7-fold difference. FP16 performance shows an architectural shift: the RX Vega 11 delivers 3.942 TFLOPS at a 2:1 ratio, while the RX 9070 XT matches its FP32 at 48.66 TFLOPS with a 1:1 ratio.

Memory architecture is another fundamental split. The RX Vega 11 relies on system-shared memory with no dedicated VRAM, making bandwidth entirely dependent on the host system. The RX 9070 XT brings 16 GB of GDDR6 on a 256-bit bus, delivering 644.6 GB/s of bandwidth. API support also diverges: the RX Vega 11 supports DirectX 12 (12_1) and Vulkan 1.3, while the RX 9070 XT supports DirectX 12 Ultimate (12_2) and Vulkan 1.4. Both share OpenGL 4.6 support.

Where Each One Wins

The RX 9070 XT wins in every measurable compute and graphics scenario where both have been tested. In Geekbench OpenCL, it posts 17428 versus 12525 for the RX Vega 11. In Geekbench Vulkan, the margin expands to 65879 versus 13543. This is not a close contest in raw performance. The RX 9070 XT also has dedicated ray tracing hardware, a feature absent from the RX Vega 11, making it the only viable choice for ray-traced workloads.

The RX Vega 11, however, wins in efficiency and practicality for its intended role. As an integrated GPU with a 15 W TDP, it requires no power connectors, no dedicated slot, and draws power from the host system. The RX 9070 XT demands a 304 W TDP, dual-slot cooling, two 8-pin power connectors, and a suggested 700 W power supply. For a system where space, power, and cooling are constrained, the RX Vega 11 is the only option that fits. It also benefits from a 56th percentile ranking versus the RX 9070 XT's 55th percentile, suggesting that within their respective benchmark pools, the older part holds its own relative to contemporaries.

In terms of production status, the RX Vega 11 is end-of-life, meaning no new supply exists. The RX 9070 XT is active and currently available. For legacy systems or low-power builds, the RX Vega 11 remains a functional choice; for any modern gaming or compute workload, the RX 9070 XT is the clear winner.

Head-to-Head Benchmarks

The head-to-head data contains only two shared benchmarks, and the RX 9070 XT wins both outright. In Geekbench OpenCL, the RX 9070 XT scores 17428 against the RX Vega 11's 12525, a delta of 28.1% in favor of the newer card. This is a substantial margin, but not overwhelming — it suggests that compute workloads that scale well across many cores see a significant but not transformative improvement.

Geekbench Vulkan tells a different story. The RX 9070 XT posts 65879, while the RX Vega 11 manages 13543. That is a 79.4% difference, nearly quadrupling the OpenCL gap. Vulkan workloads that leverage the RX 9070 XT's 4096 shading units, 64 ray tracing cores, and modern RDNA 4.0 feature set simply overwhelm the RX Vega 11's 704 shading units and GCN 5.0 architecture. The RX Vega 11's nearest rivals in its own benchmark pool include the NVIDIA GeForce GTX TITAN (deltaPct 0.1%), GTX 965M (-0.1%), and Intel Iris Xe MAX Graphics (0.5%), showing it performs in line with those older parts. The RX 9070 XT's nearest rivals — AMD Radeon HD 7770M (0.1%), NVIDIA GeForce GTX 570 (0.2%), and NVIDIA P106-090 (0.5%) — are also older or lower-tier products, indicating that its average benchmark score of 13543 sits in a similar performance tier despite the vastly different workload profile.

The wins tally is unambiguous: the RX 9070 XT takes 2 wins, the RX Vega 11 takes 0. No benchmark in the shared set favors the integrated part. The average benchmark scores differ (14385 for RX Vega 11, 13543 for RX 9070 XT), but this is an artifact of different benchmark suites and should not be interpreted as the RX Vega 11 being faster — the direct comparisons show the opposite.

The Verdict

The data is clear: the AMD Radeon RX 9070 XT is the superior performer in every head-to-head benchmark available. It wins Geekbench OpenCL by 28.1% and Geekbench Vulkan by 79.4%. It offers 16 GB of dedicated GDDR6 memory, 644.6 GB/s of bandwidth, 64 ray tracing cores, and a 48.66 TFLOPS FP32 throughput. For anyone building a gaming PC, a workstation for compute tasks, or a system that needs modern API support like DirectX 12 Ultimate and Vulkan 1.4, the RX 9070 XT is the only rational choice from these two.

The AMD Radeon RX Vega 11, however, is not without its niche. As a 15 W integrated GPU with no power connectors and system-shared memory, it serves a specific purpose: low-power, compact, legacy systems. It is end-of-life, so new builds would not consider it, but existing systems with a Picasso APU can still use it for basic display output and light 2D workloads. Its 56th percentile ranking among all GPUs indicates it performed respectably in its era, but that era has passed.

Choose the RX 9070 XT if you need performance, modern features, or ray tracing. Choose the RX Vega 11 only if you are constrained to an integrated GPU on an older platform with minimal power and cooling headroom. The benchmark results do not support any other conclusion.
