NVIDIA RTX 4500 Ada Generation vs NVIDIA RTX 6000 Ada Generation Comparison

Head-to-Head Benchmarks

The data paints an unambiguous picture: the NVIDIA RTX 6000 Ada Generation dominates the RTX 4500 Ada Generation in every recorded benchmark. In Geekbench OpenCL, the RTX 6000 scores 311,629 against the RTX 4500's 160,786, a massive 93.8% advantage. That is not a marginal gap; it is nearly double the raw compute output. The gap narrows slightly in Vulkan, but the RTX 6000 still wins decisively with 262,845 points versus 171,401, a 53.4% delta. For any workload that leans on compute throughput, the RTX 6000 is in a different performance class entirely.

Looking at the broader competitive landscape reinforces this. The RTX 6000's average benchmark score of 287,237 places it in the 99th percentile of all GPUs, while the RTX 4500 sits at 166,094, which is still a strong 97th percentile showing. The RTX 6000's nearest rival, the NVIDIA L40, trails it by a slim 1.1% with an average score of 284,111, meaning the RTX 6000 is essentially at parity with that data-center card. More tellingly, the RTX 6000 leads the NVIDIA L20 by 14.4% (251,147 average score). On the RTX 4500 side, its closest competitor is the NVIDIA RTX A5500, which scores 165,217, a lead of just 0.5% for the RTX 4500. That is a razor-thin margin, suggesting the RTX 4500 is tightly clustered with previous-generation workstation parts rather than breaking new ground.

In the direct head-to-head, the RTX 6000 wins both tests. The OpenCL result shows the RTX 6000 delivering 93.8% more performance, which is the single largest delta in the comparison. The Vulkan test, while still a clear win, shows a 53.4% advantage, indicating that API overhead or driver scheduling may compress the gap somewhat in graphics-oriented tasks. Still, the pattern is consistent: the RTX 6000 is the superior card by any measurable metric in this data set.

The Verdict

The data is unequivocal: the NVIDIA RTX 6000 Ada Generation is the faster card in every benchmark recorded. If raw compute performance is the sole criterion, the RTX 6000 is the clear choice. Its average benchmark score of 287,237 is 73% higher than the RTX 4500's 166,094. The win count reflects this: two wins for the RTX 6000, zero for the RTX 4500. The 93.8% OpenCL delta is a generational leap, not an incremental improvement.

However, the choice is not purely about peak performance. The RTX 4500, with its 97th percentile ranking, is still a very capable workstation GPU. Its average score of 166,094 places it just 0.5% ahead of the RTX A5500 and 0.7% ahead of the AMD Radeon PRO W7800 (164,894). For users whose workloads are already handled comfortably by those cards, the RTX 4500 offers a modern, active product with a 210 W TDP and no external power connector required. The RTX 6000, by contrast, is end-of-life, requires a 700 W PSU, and draws 300 W.

Who should pick which? Strictly from the data, the RTX 6000 is for users who need maximum compute throughput and are willing to accept the higher power draw and end-of-life status. The RTX 4500 is for users who need a current-generation card with lower system integration demands, and who are targeting performance levels around the RTX A5500 or Radeon PRO W7800. The RTX 6000's 48 GB of memory versus the RTX 4500's 24 GB also matters for large datasets, but that is a capacity question, not a speed one. If the workload fits in 24 GB, the RTX 4500 is competitive; if it does not, the RTX 6000 is the only option in this pairing.

Specification Differences

The two cards diverge sharply on memory and compute resources. The RTX 6000 features 48 GB of GDDR6 memory on a 384-bit bus, delivering 960.0 GB/s of bandwidth. The RTX 4500 is cut down to 24 GB of GDDR6 on a 192-bit bus, yielding 432.0 GB/s. That is a 2x difference in both capacity and bandwidth, which directly impacts large-model loading and texture streaming.

The compute core counts follow a similar pattern. The RTX 6000 has 18,176 shading units, 568 TMUs, and 192 ROPs. The RTX 4500 has 7,680 shading units, 240 TMUs, and 80 ROPs. Ray tracing and tensor cores also scale: 142 RT cores and 568 tensor cores on the RTX 6000 versus 60 RT cores and 240 tensor cores on the RTX 4500. The resulting FP32 throughput is 91.06 TFLOPS for the RTX 6000 and 39.63 TFLOPS for the RTX 4500.

Clocks and power tell a different story. The RTX 6000 has a base clock of 915 MHz and a boost of 2505 MHz, while the RTX 4500 runs much higher out of the box at 2070 MHz base and 2580 MHz boost. Despite the higher clocks, the RTX 4500 draws less power: 210 W TDP versus 300 W. The RTX 4500 also requires no external power connector, while the RTX 6000 needs a single 16-pin connector. The suggested PSU is 550 W for the RTX 4500 and 700 W for the RTX 6000.

Physical dimensions differ slightly. The RTX 6000 is 267 mm long, while the RTX 4500 is 245 mm. Both are dual-slot cards with a 112 mm height and 4x DisplayPort 1.4a outputs. The RTX 6000 uses the AD102 chip, and the RTX 4500 uses AD103, with die sizes of 609 mm² and 379 mm² respectively. Transistor counts are 76,300 million for the RTX 6000 and 45,900 million for the RTX 4500.

Architecture Differences

Both cards are built on the Ada Lovelace architecture and fabricated by TSMC on a 5 nm process. The foundry and node are identical, but the silicon implementations are not. The RTX 6000 uses the full-scale AD102 die, while the RTX 4500 uses the smaller AD103 die. The transistor density is slightly higher on the RTX 6000 at 125.3M / mm² versus 121.1M / mm² on the RTX 4500, reflecting the larger chip's more efficient packing.

Memory architecture differs fundamentally. The RTX 6000 runs its GDDR6 at 2500 MHz with 20 Gbps effective speed, while the RTX 4500 runs at 2250 MHz with 18 Gbps effective. The bus width difference (384-bit vs 192-bit) is the primary driver of the bandwidth gap. Both support PCIe 4.0 x16, and both expose the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The feature sets are otherwise identical in terms of display output and API support. The key architectural difference is scale: the RTX 6000 has 2.37x the shading units, 2.37x the TMUs, 2.4x the ROPs, 2.37x the RT cores, and 2.37x the tensor cores compared to the RTX 4500. The FP16 to FP32 ratio is 1:1 on both cards, indicating no consumer-grade FP16 throttling. The RTX 6000 is marked as end-of-life with a release date of December 2022, while the RTX 4500 is active with an August 2023 release. Both share the same predecessor (Workstation Ampere) and successor (Blackwell PRO W). The RTX 6000 has a launch MSRP of 6,799 USD; the RTX 4500 has no listed launch MSRP.
