Nexus 7 Performance: Consistent With Other Tegra 3-Based Tablets
The Nexus 7 employs a slightly slower version of Nvidia's Tegra 3 called T30L, which is also found in Asus' Transformer Pad (TF300T).
| GeekBench | Transformer Pad (TF300T) | Transformer Prime (TF201) | Nexus 7 |
|---|---|---|---|
| SoC | Tegra 3 (T30L) | Tegra 3 (T30) | Tegra 3 (T30L) |
| Android | 4.0 (Ice Cream Sandwich), Performance Profile | 4.0 (Ice Cream Sandwich), Performance Profile | 4.1 (Jelly Bean) |
| Overall | 1534 | 1632 | 1527 |
| Integer | 1380 | 1399 | 1298 |
| Floating Point | 2231 | 2554 | 2288 |
| Memory | 1214 | 1100 | 1222 |
Really, the CPU performance difference between T30L and T30 is negligible. Compared to dual-core SoCs, Tegra 3 still wins easily.

The Nexus 7’s GPU delivers benchmark scores similar to the Transformer Pad T300T. The Transformer Prime falls slightly behind the Nexus because it is handicapped with 1066 MT/s LP-DDR2. The Nexus 7 and TF300T employ faster 1333 MT/s LP-DDR3, helping illustrate the impact that memory bandwidth can have on performance.
Of course, in the real world, memory throughput and capacity are rarely bottlenecks on their own. According to the benchmarks, the Nexus 7 keeps right up with the Transformer Pad (TF300T). So, if anything, we'd come to expect a consistent experience gaming on one Tegra 3-based device compared to some of the others. Ultimately, that's what we have to imagine developers really want.
