AMD Radeon Vega Frontier Edition vs NVIDIA L4 Comparison

Head-to-Head Benchmarks

The benchmark database records two direct comparisons between the NVIDIA L4 and the AMD Radeon Vega Frontier Edition, and in both cases the L4 delivers a decisive victory. In the Geekbench OpenCL test, the L4 scores 140,838 against the Vega Frontier Edition's 76,111, a gap of 85%. That is not a marginal lead; it is a generational leap in raw compute throughput. The Vulkan result tells a similar story: the L4 posts 121,306 while the Vega Frontier Edition manages 71,937, putting the L4 68.6% ahead. Both deltas are among the largest recorded between any two cards in this performance tier.

The average benchmark score for the L4 sits at 131,072, which places it in the 95th percentile of all GPUs in the database. The Vega Frontier Edition, by contrast, averages 73,370 and lands in the 91st percentile. The L4's nearest rivals include the NVIDIA GeForce RTX 3090 Ti at 131,938 (a 0.7% difference), the NVIDIA RTX 4000 Ada Generation at 135,218 (3.1% ahead), and the AMD Radeon PRO W6800 at 135,396 (3.2% ahead). The Vega Frontier Edition's closest competitors are the AMD Radeon Pro Vega 64 at 72,379 (1.4% behind), the NVIDIA TITAN X Pascal at 72,098 (1.8% behind), and the AMD Radeon RX 6650M at 71,768 (2.2% behind). The data shows that the L4 competes with modern workstation cards, while the Vega Frontier Edition trades blows with older pascal-era flagships.

In the head-to-head table, the L4 wins both recorded benchmarks, with a 2-0 wins tally. The OpenCL margin is especially striking because OpenCL workloads often favor AMD's compute-oriented architecture, yet the L4 still manages an 85% advantage. The Vulkan result is somewhat narrower at 68.6%, but that is still a commanding lead. These are not edge cases or single-threaded tasks; they are aggregate scores across the full benchmark suite, and the L4's Ada Lovelace architecture simply outclasses the older GCN 5.0 design in every measured scenario.

Architecture Differences

The architectural split between these two cards is vast, and it explains the benchmark outcomes. The NVIDIA L4 uses the AD104 chip built on TSMC's 5 nm process, packing 35,800 million transistors onto a 294 mm² die, which yields a transistor density of 121.8 million per square millimeter. The AMD Radeon Vega Frontier Edition uses the Vega 10 chip on GlobalFoundries' 14 nm process, with 12,500 million transistors spread across a much larger 495 mm² die, giving a density of just 25.3 million per square millimeter. The L4 is not only denser but also significantly more efficient in terms of raw transistor count per area.

Core configurations differ sharply. The L4 has 7,424 shading units, 240 texture mapping units, and 80 render output units, plus 60 dedicated ray tracing cores and 240 tensor cores. The Vega Frontier Edition has 4,096 shading units, 256 TMUs, and 64 ROPs, but no ray tracing cores and no tensor cores. The L4's FP32 throughput is 30.29 TFLOPS, while the Vega Frontier Edition manages 13.11 TFLOPS. In FP16, the L4 delivers 30.29 TFLOPS at a 1:1 ratio, whereas the Vega Frontier Edition offers 26.21 TFLOPS at a 2:1 ratio, meaning it halves its throughput for FP16 workloads that require full precision.

Memory subsystems also diverge. The L4 uses 24 GB of GDDR6 on a 192-bit bus, providing 300.1 GB/s of bandwidth. The Vega Frontier Edition uses 16 GB of HBM2 on a 2048-bit bus, delivering 483.8 GB/s. The Vega card has a massive bandwidth advantage (61% higher), but the L4's superior compute throughput more than compensates in the recorded benchmarks. Clock speeds tell a similar story: the L4 runs at a 795 MHz base and 2040 MHz boost, while the Vega Frontier Edition runs at 1382 MHz base and 1600 MHz boost. The L4's higher boost clock, combined with its newer architecture, gives it a significant per-clock instruction throughput advantage.

Power and physical design differ as well. The L4 has a TDP of 72 W and draws power from the PCIe slot alone, with no external power connectors, and it occupies a single slot. The Vega Frontier Edition has a TDP of 300 W, requires two 8-pin connectors, and takes up a dual-slot space. The L4's suggested PSU is 250 W, while the Vega card needs a 700 W unit. The L4 is also much smaller: 169 mm long and 56 mm high versus 267 mm long and 111 mm high for the Vega card. The L4 has no display outputs, whereas the Vega Frontier Edition offers one HDMI 2.0b port and three DisplayPort 1.4a outputs.

Where Each One Wins

The NVIDIA L4 wins in every benchmark category recorded in the database, but the nature of those wins points to specific workload advantages. In OpenCL, the L4's 85% lead suggests it excels at compute-heavy tasks such as machine learning inference, scientific simulation, and data processing. The presence of tensor cores and ray tracing cores in the L4 architecture further extends its dominance into AI acceleration and real-time ray tracing workloads, even though those specific tests are not directly recorded in the head-to-head data.

The AMD Radeon Vega Frontier Edition's only potential edge lies in its memory bandwidth and its display outputs. With 483.8 GB/s of bandwidth, the Vega card can feed data to its 4,096 shading units faster than the L4 can to its 7,424 units, which could benefit memory-bound workloads such as large matrix operations or video processing that require constant data streaming. Additionally, the Vega Frontier Edition's HDMI and DisplayPort outputs make it usable in a workstation with direct display connectivity, whereas the L4 is a headless server card with no outputs.

In terms of power efficiency, the L4 is decisively ahead. It delivers 30.29 TFLOPS of FP32 performance at 72 W, which translates to roughly 0.42 TFLOPS per watt. The Vega Frontier Edition delivers 13.11 TFLOPS at 300 W, which is about 0.044 TFLOPS per watt. The L4 is nearly ten times more efficient in raw compute per watt, and its 169 mm length makes it far easier to fit into dense server chassis. The Vega card's 267 mm length and dual-slot footprint limit its deployability in modern rack environments.

Specification Differences

The specification table shows clear divergence across nearly every field. The L4 uses a 5 nm process, while the Vega Frontier Edition uses 14 nm. Transistor counts are 35,800 million versus 12,500 million, and die sizes are 294 mm² versus 495 mm². The L4's base clock is 795 MHz, notably lower than the Vega's 1382 MHz, but the L4's boost clock reaches 2040 MHz versus the Vega's 1600 MHz. Memory configurations differ: the L4 has 24 GB of GDDR6 on a 192-bit bus with 300.1 GB/s bandwidth, while the Vega has 16 GB of HBM2 on a 2048-bit bus with 483.8 GB/s bandwidth. Memory clock rates are 1563 MHz (12.5 Gbps effective) for the L4 and 945 MHz (1890 Mbps effective) for the Vega.

Compute units differ: the L4 has 7,424 shading units, 240 TMUs, and 80 ROPs, while the Vega has 4,096 shading units, 256 TMUs, and 64 ROPs. The L4 adds 60 ray tracing cores and 240 tensor cores; the Vega has none. Pixel and texture rates: the L4 achieves 163.2 GPixel/s and 489.6 GTexel/s, while the Vega achieves 102.4 GPixel/s and 409.6 GTexel/s. FP32 performance is 30.29 TFLOPS versus 13.11 TFLOPS, and FP16 is 30.29 TFLOPS (1:1) versus 26.21 TFLOPS (2:1). The L4's TDP is 72 W with no power connectors and a 250 W suggested PSU, while the Vega's TDP is 300 W with two 8-pin connectors and a 700 W suggested PSU. The L4 is single-slot and 169 mm long, 56 mm high, while the Vega is dual-slot and 267 mm long, 111 mm high. The L4 has no display outputs, while the Vega has one HDMI 2.0b and three DisplayPort 1.4a outputs. The L4 uses PCIe 4.0 x16, the Vega uses PCIe 3.0 x16. API support: the L4 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4; the Vega supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The L4 was released on March 20, 2023, and is still active in production; the Vega Frontier Edition was released on June 26, 2017, and is end-of-life. The Vega's launch MSRP was 999 USD.
