Intel now has two dual-core nettop CPUs based on Pine Trail technology – Intel Atom D510 and Intel Atom D525.
Like D510, D525 features Intel's 45nm Atom architecture introduced in 2008 and integrates a memory controller, DMI link and GMA 3150 graphics core. Unlike D510 though, D525 supports DDR3 memory and runs a faster clock speed. Performance-wise, D525 is expected to do better than its predecessor, of course -- but exactly by how much?
I turned to Passmark for a clear answer.
Passmark CPU Benchmark results (“Baselines”) were gathered from users’ submissions to the PassMark web site as well as from internal testing. PerformanceTest conducts eight different tests and then averages the results together to determine the CPU Mark for a system. These eight tests are as follows:
1. Integer Maths Test
2. Compression Test
3. Prime Number Test
4. Encryption Test
5. Floating Point Math Test
6. SSE/3D Now Test
7. SSE stands for Streaming SIMD extensions.
8. String Sorting Test
To ensure that the full CPU power of a PC system is realized, PerformanceTest runs each CPU test on all available CPUs. Specifically, PerformanceTest runs one simultaneous CPU test for every logical CPU (Hyper-threaded); physical CPU core (dual core) or physical CPU package (multiple CPU chips). So hypothetically if you have a PC that has two CPUs, each with dual cores that use hyper-threading then PerformanceTest will run eight simultaneous tests.
Here's a comparative chart showing Passmark CPU benchmarks of both D510 and D525 as of July 16, 2010 -- I also included N270 benchmark results just to show you how much better Pineview is vs. Diamondville in terms of performance:
Here we can see a big improvement from Diamondville to Pineview but a relatively small increase in performance from D510 to D525. However, this slight improvement is enough to make D525 better than 3 Intel Core Ultra-Low Voltage CPUs that are more powerful than D510:
