Need advice which card to use

Hi,

After two weeks start to learn OpenCL, I want to buy an ATI Radeon HD card. Based on my budget and my current PC (AMD Athlon 64 X2 Dual Core Processor,  250 watt power supply), I looked at the information provided on AMD website about card supported OpenCL.

I want to choose among these three: HD 5450, HD 5570, and HD 5670. Anybody can share their experience of using these cards ? Actually, I prefer HD 5570 (because of its low power)

Thank you

You should tell us what you want to achieve with OpenCL and the card.

Just want to use for practice OpenCL. Run simple operations such as matrix addition, multiplication. (at least it can run the samples from AMD stream SDK, because I learn using the provided examples in the SDK)

Unless I'm misunderstanding the specs, it looks like the 5450 has only one compute unit. (80 streaming processors per compute.) If that's the case you may be happier with one of the others, which look like they have 5 a piece.

sblackwell,
The 5450 has 2 SIMD's of 1/2 the size. The 5570 and the 5670 has 5 full size SIMD's.

hi c0nfig,

Run clInfo sample.Under Gpu Section it mentions the openCL spec supported.

All R770 generation devices support only openCL 1.0 and not 1.1.

Thanks

Nou, that is not entirely correct.
All cards that are based on the 7XX generation of chips support OpenCL 1.0, and all cards based on the Evergreen generation of chips support OpenCL 1.1. There are some cards that are labeled as 4XXX that are 6XX chips and some cards that are labeled as 5XXX that are 7XX chips.
See http://en.wikipedia.org/wiki/C...phics_processing_units for more information.
