AMD Radeon Vega Frontier Edition vs AMD Radeon VII Comparison

AMD Radeon Vega Frontier Edition and AMD Radeon VII are two professional-grade GPUs from AMD separated by roughly 20 months of architectural refinement. The data shows a clear generational shift: the Radeon VII wins all three head-to-head benchmark comparisons, with its largest advantage appearing in Vulkan workloads. However, the Vega Frontier Edition holds a slightly higher overall percentile ranking, illustrating that raw benchmark wins do not always translate to a higher aggregate position.

Head-to-Head Benchmarks

The benchmark comparison between these two cards is one-sided, with the AMD Radeon VII taking all three available tests. The largest margin comes in Geekbench Vulkan, where the Radeon VII scores 91,788 against the Vega Frontier Edition’s 71,937—a 21.6% advantage. This is a substantial gap that suggests the newer architecture handles Vulkan’s explicit multi-threading and command-buffer model more efficiently.

In Geekbench OpenCL, the Radeon VII again dominates, posting 91,947 versus 76,111 for the Vega Frontier Edition, a 17.2% delta. The smallest win for the Radeon VII is in Geekbench Metal, where it scores 77,975 against 72,061, still a solid 7.6% lead. Across all three tests, the Radeon VII averages a 15.5% advantage, though the exact figure varies by API.

Looking at the average benchmark score, the picture becomes more nuanced. The Vega Frontier Edition posts an average of 73,370, while the Radeon VII averages 66,004. This is counterintuitive given the head-to-head results, but it reflects the broader benchmark set each card was tested against. The Vega Frontier Edition sits at the 91st percentile of all GPUs, one point higher than the Radeon VII’s 90th percentile.

The nearest rival data adds context. The Vega Frontier Edition edges out the AMD Radeon Pro Vega 64 by 1.4% and the NVIDIA TITAN X Pascal by 1.8%, with smaller margins over the Radeon RX 6650M (2.2%) and RX 6600 LE (3.6%). The Radeon VII trails the NVIDIA Tesla T4 by 1.1% but beats the Tesla P40 by 1.4%, the Radeon Pro WX 9100 by 2.8%, and the NVIDIA CMP 30HX by 3.4%. These deltas show both cards are competitive within their respective peer groups, but the Radeon VII’s rivals are generally lower-scoring than the Vega Frontier’s.

Architecture Differences

The two GPUs represent successive iterations of AMD’s GCN design. The Vega Frontier Edition uses the Vega 10 chip built on GCN 5.0 architecture, fabricated on a 14 nm process at GlobalFoundries. The Radeon VII moves to the Vega 20 chip with GCN 5.1 architecture, manufactured by TSMC on a 7 nm node—a significant process shrink that affects density and efficiency.

Transistor counts differ modestly: the Vega 10 packs 12,500 million transistors across a 495 mm² die, yielding a density of 25.3 million transistors per square millimeter. The Vega 20 has 13,230 million transistors on a much smaller 331 mm² die, achieving 40.0 million per square millimeter. That is a 58% improvement in transistor density, enabled by the 7 nm process.

The Radeon VII’s memory subsystem is a major differentiator. Both cards feature 16 GB of HBM2, but the Radeon VII doubles the bus width to 4096 bit, pushing bandwidth to 1.02 TB/s—more than double the Vega Frontier Edition’s 483.8 GB/s on its 2048-bit bus. Effective memory clock also rises from 1890 Mbps to 2 Gbps.

Shader configuration is reversed from what the process node might suggest. The Vega Frontier Edition has 4096 shading units, 256 TMUs, and 64 ROPs. The Radeon VII has 3840 shading units and 240 TMUs, with the same 64 ROPs. Despite fewer cores, the Radeon VII achieves higher clock speeds: 1400 MHz base and 1750 MHz boost versus 1382 MHz and 1600 MHz. This yields slightly higher compute rates—13.44 TFLOPS FP32 and 26.88 TFLOPS FP16 versus 13.11 and 26.21 TFLOPS.

Neither card has ray tracing or tensor cores, and both support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. Power consumption is nearly identical at 300 W for the Vega Frontier and 295 W for the Radeon VII, with the latter recommending a 600 W PSU versus 700 W for the former.

Specification Differences

The two cards differ in nearly every major specification category. The process node moves from 14 nm to 7 nm, and the foundry shifts from GlobalFoundries to TSMC. Transistor count rises from 12,500 million to 13,230 million, while die size shrinks from 495 mm² to 331 mm². Transistor density improves from 25.3M per mm² to 40.0M per mm².

Clock speeds increase on the Radeon VII: base clock goes from 1382 MHz to 1400 MHz, boost from 1600 MHz to 1750 MHz, and memory clock from 945 MHz (1890 Mbps effective) to 1000 MHz (2 Gbps effective). Memory bus width doubles from 2048 bit to 4096 bit, and bandwidth jumps from 483.8 GB/s to 1.02 TB/s.

The compute configuration changes: shading units drop from 4096 to 3840, TMUs from 256 to 240, while ROPs stay at 64. Pixel rate rises from 102.4 GPixel/s to 112.0 GPixel/s, and texture rate from 409.6 GTexel/s to 420.0 GTexel/s. FP32 and FP16 both increase slightly—from 13.11 to 13.44 TFLOPS and 26.21 to 26.88 TFLOPS, respectively.

Power specifications are close but not identical: TDP drops from 300 W to 295 W, and suggested PSU from 700 W to 600 W. Physical dimensions grow on the Radeon VII: length from 267 mm to 280 mm, height from 111 mm to 125 mm, and it gains a width specification of 40 mm. The Vega Frontier Edition has no listed width.

Release dates differ by roughly 20 months, with the Vega Frontier Edition launching on 2017-06-26 and the Radeon VII on 2019-02-06. The architecture generation changes from "Radeon Pro Vega (Vega Series)" to "Vega II (Radeon VII)." The launch MSRP also differs: 999 USD for the Vega Frontier Edition versus 699 USD for the Radeon VII.

Where Each One Wins

The Radeon VII wins decisively in all shared benchmark tests. Its strongest showing is in Vulkan, where the 21.6% lead indicates superior API utilization. The OpenCL advantage of 17.2% suggests strong general-purpose compute performance, and even the smallest win—7.6% in Metal—shows consistent superiority across APIs. The Radeon VII also wins on memory bandwidth, clock speeds, and raw compute throughput in FP32 and FP16.

The Vega Frontier Edition wins on aggregate benchmark standing. Its 91st percentile ranking versus the Radeon VII’s 90th, combined with a higher average benchmark score of 73,370 versus 66,004, indicates it performs better across a wider range of tests beyond the three shared ones. The Vega Frontier Edition also has more shading units (4096 versus 3840) and TMUs (256 versus 240), which can benefit certain workloads that scale with core count rather than clock speed.

In terms of physical footprint, the Vega Frontier Edition is shorter (267 mm versus 280 mm) and shorter in height (111 mm versus 125 mm), which may matter for case compatibility. It also has a slightly lower TDP relative to its performance class, though the difference is small. The Vega Frontier Edition’s 16 GB of HBM2 memory at 483.8 GB/s is still substantial, even if the Radeon VII doubles that bandwidth.

The Verdict

The data points to a clear split: the Radeon VII is the faster card in direct comparison, winning every shared benchmark by margins ranging from 7.6% to 21.6%. Its 7 nm process, doubled memory bus width, and higher clock speeds deliver measurable performance gains across Metal, OpenCL, and Vulkan. For users prioritizing raw speed in these specific APIs, the Radeon VII is the superior choice.

The Vega Frontier Edition, however, holds a better aggregate position at the 91st percentile with a higher average benchmark score. This suggests it performs more consistently across a broader suite of tests, even if it loses in the three head-to-head comparisons. Its higher shading unit count and lower launch MSRP (999 USD versus 699 USD, stated once here) may also appeal to certain compute workloads that favor wider SIMD configurations.

Ultimately, the choice depends on workload. Applications that leverage OpenCL or Vulkan will see a significant boost from the Radeon VII. Those that rely on a wider range of benchmarks or favor core-count scaling may find the Vega Frontier Edition more balanced. Both cards are end-of-life products, so availability and driver support are equal considerations. The benchmark data alone suggests the Radeon VII for API-specific performance, while the Vega Frontier Edition for overall percentile standing.
