AMD Radeon RX 7600M vs NVIDIA Tesla T4 Comparison

The NVIDIA Tesla T4 and AMD Radeon RX 7600M represent two distinct philosophies in GPU design: one a legacy server accelerator, the other a modern mobile part. The data shows a single head-to-head benchmark result, with the AMD Radeon RX 7600M taking the win in Geekbench OpenCL with a score of 63775 against the Tesla T4's 61276, a delta of -3.9% from the perspective of the NVIDIA card. This places the RX 7600M roughly 4% ahead of the Tesla T4 in raw compute throughput, a margin that is notable given the T4's data-center pedigree. However, the overall benchmark landscape is more nuanced. The Tesla T4 holds a 90th percentile ranking among all GPUs, with an average benchmark score of 66733, while the RX 7600M sits just one point lower at the 89th percentile, with an average score of 63775. This suggests that while the RX 7600M wins the specific OpenCL test, the Tesla T4's broader performance profile, likely bolstered by its other benchmark result in Geekbench Vulkan (72190), keeps it competitive in the wider ecosystem.

Head-to-Head Benchmarks

The only direct comparison available is the Geekbench OpenCL test, where the AMD Radeon RX 7600M emerges victorious. The RX 7600M scores 63775, while the NVIDIA Tesla T4 trails at 61276. This represents a 3.9% performance deficit for the T4, a statistically significant margin in synthetic workloads. The result is interesting because it flips the expected narrative: the Tesla T4, with its higher average benchmark score and better percentile ranking, is beaten in this specific compute test.

Looking at the nearest rivals for each card provides context for this head-to-head. The Tesla T4's average score of 66733 places it 1.1% ahead of the AMD Radeon VII (66004) and 2.5% ahead of the NVIDIA Tesla P40 (65095). Conversely, it falls 2.7% behind the AMD Radeon Instinct MI25 (68562) and 3% behind the Intel Arc A770 (68809). The RX 7600M, with its average score of 63775, is nearly identical to its closest rivals: it is 0.1% behind the AMD Radeon RX 9060 XT LP (63830) and 0.1% behind the NVIDIA CMP 30HX (63842). It sits 0.1% ahead of the AMD Radeon Pro Vega 56 (63693) and 0.7% behind the AMD Radeon Pro WX 9100 (64212). This data indicates that the RX 7600M's victory in the head-to-head is not an outlier in its own performance class, but rather a consistent level of output for that chip.

The data shows that the Tesla T4's higher average score is driven by its Vulkan performance, which is not compared directly against the RX 7600M. The T4's Vulkan score of 72190 is substantially higher than its OpenCL score, suggesting that it excels in APIs that leverage its specific hardware features. The RX 7600M has no Vulkan result in the fact pack, leaving a gap in the comparative analysis. Therefore, while the RX 7600M wins the single available benchmark, the Tesla T4 demonstrates superior performance in another API that the RX 7600M has not matched.

Where Each One Wins

The AMD Radeon RX 7600M wins the compute workload represented by Geekbench OpenCL, posting a 3.9% higher score than the Tesla T4. This suggests that for general-purpose compute tasks that utilize OpenCL, the RX 7600M holds an advantage. Given its higher FP32 throughput of 17.27 TFLOPS compared to the T4's 8.141 TFLOPS, this result is consistent with the raw compute specifications. The RX 7600M also has a higher boost clock of 2410 MHz versus the T4's 1590 MHz, which contributes to its superior computational throughput in shader-heavy workloads.

The NVIDIA Tesla T4, on the other hand, wins in the broader benchmark landscape. Its average benchmark score of 66733 is 4.5% higher than the RX 7600M's 63775. This is largely attributable to its strong Vulkan score of 72190, which is 17.7% higher than its own OpenCL score. This suggests that the T4 is particularly well-suited for workloads that utilize the Vulkan API, potentially due to its dedicated RT cores and Tensor Cores. The T4 also holds a higher percentile ranking (90th) versus the RX 7600M (89th), indicating that it outperforms a slightly larger fraction of the GPU population in the benchmark database.

In terms of memory, the Tesla T4 offers a significant capacity advantage with 16 GB of GDDR6 memory, double the 8 GB found on the RX 7600M. The T4 also has a wider 256-bit memory bus, resulting in higher memory bandwidth of 320.0 GB/s versus the RX 7600M's 256.0 GB/s. This makes the T4 better suited for large datasets and memory-intensive workloads, even though its raw compute is lower. The RX 7600M counters with a smaller, more compact design (IGP form factor), and a newer PCIe 4.0 x16 interface, which offers double the bandwidth of the T4's PCIe 3.0 x16 connection.

Architecture Differences

The architectural divide between these two GPUs is stark. The NVIDIA Tesla T4 is built on the Turing architecture, fabricated on a 12 nm process at TSMC. It uses a massive TU104 chip with 13,600 million transistors on a 545 mm² die, yielding a transistor density of 25.0M / mm². The AMD Radeon RX 7600M, in contrast, uses the RDNA 3.0 architecture and a Navi 33 chip, built on a more advanced 6 nm process at TSMC. This chip packs 13,300 million transistors into a much smaller 204 mm² die, achieving a significantly higher transistor density of 65.2M / mm². The process node advantage is clear: the RX 7600M packs nearly the same number of transistors into less than half the silicon area.

The compute resources differ fundamentally. The Tesla T4 has 2560 shading units, 160 TMUs, and 64 ROPs. It also includes 40 RT cores and 320 Tensor Cores, making it a purpose-built accelerator for ray tracing and AI inference. The RX 7600M has fewer shading units (1792), TMUs (112), and ROPs (64), but it compensates with much higher clock speeds. It also includes 28 RT cores but has no Tensor Cores, indicating a different focus on gaming and general compute rather than dedicated AI acceleration. The absence of Tensor Cores in the RX 7600M is a key architectural differentiator, as the T4's 320 Tensor Cores are designed for matrix operations.

Clock speeds are a major point of divergence. The Tesla T4 has a low base clock of 585 MHz and a boost clock of 1590 MHz, likely to manage its 70 W TDP. The RX 7600M, with a 90 W TDP, runs much faster: a base clock of 1500 MHz, a game clock of 2070 MHz, and a boost clock of 2410 MHz. This 820 MHz boost clock advantage translates directly into the RX 7600M's superior pixel and texture rates. The T4 produces 101.8 GPixel/s and 254.4 GTexel/s, while the RX 7600M produces 154.2 GPixel/s and 269.9 GTexel/s. The RX 7600M's pixel rate is 51.5% higher, and its texture rate is 6.1% higher, despite having fewer TMUs.

Memory architecture also differs. The Tesla T4 uses a 256-bit memory bus with 16 GB of GDDR6 memory at 10 Gbps effective, achieving 320.0 GB/s bandwidth. The RX 7600M uses a narrower 128-bit bus with 8 GB of GDDR6 memory at 16 Gbps effective, achieving 256.0 GB/s bandwidth. While the T4 has more total bandwidth, the RX 7600M's memory operates at a faster effective speed, which can be an advantage for latency-sensitive tasks. The T4's larger memory pool is a clear advantage for server workloads, while the RX 7600M's smaller pool is typical for mobile gaming.

Specification Differences

The two cards differ across nearly every specification field. The most obvious difference is the form factor: the Tesla T4 is a single-slot, 168 mm (6.6 inches) long card designed for server chassis, while the RX 7600M is an IGP (Integrated Graphics Processor) designed for mobile devices. The Tesla T4 has no display outputs, while the RX 7600M's display outputs are "portable device dependent," meaning they are integrated into the host system. The T4 requires no external power connectors and has a suggested PSU of 250 W, while the RX 7600M also has no power connectors but lists no suggested PSU.

The TDPs differ, with the Tesla T4 rated at 70 W and the RX 7600M at 90 W. The process node is a key difference: 12 nm for the T4 versus 6 nm for the RX 7600M. The transistor count is nearly identical (13,600 million vs 13,300 million), but the die sizes are vastly different (545 mm² vs 204 mm²), leading to a 2.6x difference in transistor density (25.0M / mm² vs 65.2M / mm²). The bus interface differs as well: the T4 uses PCIe 3.0 x16, while the RX 7600M uses the newer PCIe 4.0 x16.

Memory size is a significant differentiator: 16 GB on the T4 versus 8 GB on the RX 7600M. Memory bandwidth also favors the T4 at 320.0 GB/s versus 256.0 GB/s. The memory clock is listed as 1250 MHz (10 Gbps effective) for the T4 and 2000 MHz (16 Gbps effective) for the RX 7600M. The shading units (2560 vs 1792), TMUs (160 vs 112), and RT cores (40 vs 28) all favor the T4 in count, but the RX 7600M's higher clocks close the performance gap. The T4 has 320 Tensor Cores, a feature entirely absent from the RX 7600M. FP32 performance heavily favors the RX 7600M at 17.27 TFLOPS versus 8.141 TFLOPS, a 112% difference. FP16 performance similarly favors the RX 7600M at 34.55 TFLOPS versus 16.28 TFLOPS. The release dates are years apart: September 2018 for the T4 and January 2023 for the RX 7600M, with the T4 marked as end-of-life and the RX 7600M as active.
