NVIDIA L4 vs NVIDIA TITAN X Pascal Comparison

Head-to-Head Benchmarks

The recorded data contains two cross-generational benchmark comparisons between the NVIDIA L4 and the NVIDIA TITAN X Pascal, and in both tests the L4 takes a commanding lead. In Geekbench OpenCL, the L4 posts a score of 140,838 against the TITAN X Pascal’s 66,696, a difference of 111.2%. This is not a narrow margin; it represents more than double the compute output in a workload that stresses raw shader throughput and memory bandwidth. The Vulkan test narrows the gap somewhat, but the result is still decisive: the L4 scores 121,306 versus 77,499, a 56.5% advantage. Across the two benchmarks, the L4 wins 2, the TITAN X Pascal wins 0.

To contextualize the L4’s OpenCL result, the database places it at the 95th percentile among all GPUs, with an average benchmark score of 131,072. Its nearest rivals include the NVIDIA GeForce RTX 3090 Ti (average score 131,938, a delta of -0.7%), the NVIDIA RTX 4000 Ada Generation (135,218, -3.1%), the NVIDIA A10M (135,230, -3.1%), and the AMD Radeon PRO W6800 (135,396, -3.2%). In other words, the L4’s OpenCL performance sits just below the RTX 3090 Ti, within a single percentage point, and only a few points behind professional workstation cards like the RTX 4000 Ada and A10M. The TITAN X Pascal, by contrast, holds the 91st percentile, with an average score of 72,098, and its nearest rivals are all AMD cards: the Radeon Pro Vega 64 (72,379, -0.4%), the Radeon RX 6650M (71,768, 0.5%), the Radeon RX 6600 LE (70,829, 1.8%), and the Radeon Vega Frontier Edition (73,370, -1.7%). That puts the TITAN X Pascal in a much lower performance tier, roughly half the L4’s average output.

The Vulkan result tells a similar story but with a smaller margin. The L4’s 121,306 is a strong showing for a low-power server card, while the TITAN X Pascal’s 77,499 indicates that even its older GCN-era competitors, such as the Radeon Vega Frontier Edition, are within striking distance. The delta of 56.5% is still a clear victory for the L4, but it is importantly the TITAN X Pascal’s Vulkan score is relatively better than its OpenCL score, suggesting that its architecture handles modern API workloads somewhat more efficiently than legacy compute paths. Even so, the L4’s newer architecture and dedicated ray tracing and tensor hardware give it a decisive edge in both API environments.

The Verdict

The data points to a straightforward conclusion: the NVIDIA L4 is the superior card by every measured metric. Its average benchmark score of 131,072 is nearly double the TITAN X Pascal’s 72,098, and it wins both head-to-head tests by margins of 111.2% and 56.5%. The L4 also sits at the 95th percentile of all GPUs, whereas the TITAN X Pascal is at the 91st percentile, a smaller gap in percentile terms but a massive one in raw scores. For anyone choosing between these two based solely on benchmark data, the L4 is the obvious pick.

However, the TITAN X Pascal is not without a case, though that case rests on legacy factors rather than performance. It is an end-of-life product, released much earlier, and its launch MSRP was 1,199 USD, which the database records but does not adjust for inflation or market changes. The TITAN X Pascal’s 12 GB of GDDR5X memory on a 384-bit bus delivers 480.4 GB/s of bandwidth, which is higher than the L4’s 300.1 GB/s. In bandwidth-sensitive workloads that predate the L4’s architecture, the TITAN X Pascal could still hold its own. But the benchmark data shows that this bandwidth advantage does not translate into higher scores in OpenCL or Vulkan.

The L4’s wins are not marginal; they are overwhelming. In OpenCL, the 111.2% delta means the L4 completes tasks in roughly half the time. In Vulkan, the 56.5% delta still represents a significant time savings. The verdict is therefore clear: for any current workload measured by these benchmarks, the L4 is the stronger processor. The TITAN X Pascal remains a capable card in its own right, but it is outclassed by two generations of architectural progress.

Where Each One Wins

The NVIDIA L4 wins in every benchmark recorded in the database. Its 140,838 OpenCL score and 121,306 Vulkan score are both far ahead of the TITAN X Pascal’s 66,696 and 77,499. The L4’s wins are driven by its Ada Lovelace architecture, which includes 60 RT cores and 240 tensor cores, features the TITAN X Pascal lacks entirely. These dedicated units accelerate ray tracing and AI workloads, which likely explains the large Vulkan delta, as Vulkan can offload certain tasks to these specialized cores. The L4 also has 7,424 shading units versus 3,584, more than double the shader count, and its FP32 throughput of 30.29 TFLOPS dwarfs the TITAN X Pascal’s 10.97 TFLOPS.

The TITAN X Pascal does have a few theoretical advantages that could matter in niche scenarios, though the benchmarks do not capture them. Its 384-bit memory bus and 480.4 GB/s bandwidth exceed the L4’s 192-bit bus and 300.1 GB/s. For workloads that are purely memory-bound and do not leverage the L4’s newer features, such as certain scientific simulations or large dataset processing, the TITAN X Pascal’s bandwidth could narrow the gap. Its 96 ROPs also exceed the L4’s 80, which may benefit fill-rate-heavy tasks at lower resolutions. But these are speculative advantages; the recorded data shows no test where the TITAN X Pascal wins.

The L4 also wins on power efficiency, a critical factor for server deployments. Its 72 W TDP is a fraction of the TITAN X Pascal’s 250 W, and it requires no power connectors, drawing entirely from the PCIe slot, whereas the TITAN X Pascal needs a 6-pin and an 8-pin connector. The L4’s suggested PSU is 250 W, versus 600 W for the TITAN X Pascal. This makes the L4 suitable for dense server environments where power and cooling are constrained, while the TITAN X Pascal demands a more robust platform.

Architecture Differences

The NVIDIA L4 is built on the AD104 chip using the Ada Lovelace architecture, fabricated on a 5 nm process at TSMC. It packs 35,800 million transistors into a 294 mm² die, yielding a transistor density of 121.8 million per mm². The TITAN X Pascal, by contrast, uses the GP102 chip with the Pascal architecture, on a 16 nm process, also at TSMC. It contains 11,800 million transistors on a much larger 471 mm² die, giving a density of just 25.1 million per mm². The L4’s manufacturing advantage is stark: more than four times the transistor density, which explains how it fits far more compute units into a smaller package.

The L4 features 7,424 shading units, 240 TMUs, and 80 ROPs. It also includes 60 RT cores and 240 tensor cores, which are absent from the TITAN X Pascal entirely. The TITAN X Pascal has 3,584 shading units, 224 TMUs, and 96 ROPs. Its FP32 throughput is 10.97 TFLOPS, while the L4 reaches 30.29 TFLOPS. For FP16, the L4 offers 30.29 TFLOPS at a 1:1 ratio, whereas the TITAN X Pascal provides only 171.5 GFLOPS at a 1:64 ratio, a massive difference for mixed-precision workloads. The L4’s pixel rate is 163.2 GPixel/s and texture rate is 489.6 GTexel/s, against the TITAN X Pascal’s 147.0 GPixel/s and 342.9 GTexel/s.

The API support also differs. The L4 supports DirectX 12 Ultimate (12_2), while the TITAN X Pascal supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The L4’s higher DirectX feature level reflects its modern architecture, which includes hardware ray tracing and variable-rate shading support.

Specification Differences

The two cards diverge across nearly every specification. The L4 has 24 GB of GDDR6 memory, while the TITAN X Pascal has 12 GB of GDDR5X. The memory bus widths are 192-bit for the L4 and 384-bit for the TITAN X Pascal. Despite the wider bus, the TITAN X Pascal’s bandwidth of 480.4 GB/s exceeds the L4’s 300.1 GB/s, but the L4’s larger capacity and newer memory type offset this in practice.

Clock speeds differ substantially. The L4 runs at a base clock of 795 MHz and a boost of 2040 MHz, while the TITAN X Pascal has a base of 1417 MHz and a boost of 1531 MHz. The L4’s lower base clock but much higher boost indicates a design that scales aggressively under load, whereas the TITAN X Pascal runs closer to its maximum at all times. Memory clocks are 1563 MHz (12.5 Gbps effective) for the L4 and 1251 MHz (10 Gbps effective) for the TITAN X Pascal.

Physical and power characteristics are also distinct. The L4 is a single-slot card measuring 169 mm in length and 56 mm in height, with no power connectors and a 72 W TDP. The TITAN X Pascal is a dual-slot card at 267 mm long, 112 mm high, and 40 mm wide, requiring a 6-pin and an 8-pin connector with a 250 W TDP. The L4 has no display outputs, while the TITAN X Pascal offers 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.4a. The bus interface is PCIe 4.0 x16 for the L4 versus PCIe 3.0 x16 for the TITAN X Pascal. The L4 is active in production, released much later, while the TITAN X Pascal is end-of-life.
