AMD A8-3850 & Gigabyte A75M-UD2H Review

SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility capable of benchmarking the performance of individual components inside a PC.

CPU Arithmetic

The CPU arithmetic test ascertains the processor's capabilities in terms of numerical operations. Two subtests named Dhrystone and Whetstone are carried out respectively. This is not a measure of latency and thus higher is better.

Clock for clock, it is immediately apparent that the A8-3850 isn't much of an improvement over its older Athlon II X4 sibling. Do bear in mind however that the Core i5 2300 is some 30% more expensive. That said, it is also clear that from a CPU perspective, a further 30-40 pounds can go a long way.


Cache Bandwidth

Without doubt, onboard cpu cache bandwidth is very fast indeed, but will our Core i5 2300 processor perform any differently between the two motherboards?

A similar story is painted with cache bandwidth. The AMD's score is far from abysmal, mind.


Memory Performance

SiSoft Sandra offers both memory bandwidth and latency based benchmarks. It is quite possible that architectural tweaks will have made a significant impact in terms of both throughput and latency.

A major observation of the LGA1155 Sandy Bridge processors, which we reviewed in January was that they produce exceptional memory bandwidth results despite using a dual channel system. The new FM1 platform simply cannot match this at default frequencies however the results are very much in line with the Socket AM3 family.


Again, another loss in the memory department; nothing major to worry about however.

This is going to be a very hard product to review.

Mostly because there is nothing else like it on the market.

I'm a little confused as to why this was pitted against an I5 when the I5 is clearly far more expensive.

£103.99 inc for the Llano from Ebuyer, £137 inc for the I5.

The comparissons should be against the I3. Now sure, as a CPU the I3 is faster. However, the GPU aboard the 3850 poos on the I3 and is actually playable at sensible resolutions. Every other review I have read have pitted it like for like, so I can't understand why this has been benched against a CPU that puts another 35% on top of what the 3850 costs.

I can only summise it was because OC3D maybe didn't have an I3 to put it against?Quote

I agree but nice review!Quote

Oh FFS Gigabyte, I want vomit when I see SATA ports stick straight out of motherboard. Yeah this motherboard has some odd mix of price, IGP, and Crossfire capability.Quote

Thank you. I haven't published anything since February - glad to have been able to help out a little

Indeed an i3 wasn't available to compare it with, however I had left hints along the way that the price of the A8-3850 accounts for its inferior core for core and clock for clock (gag) performance. However, I feel that the article was able to highlight what was most important. Entry level multimedia users don't need outright core processor performance - combine an average CPU with a good enough GPU and their most complex needs are satisfied. Intel's Atom + nVidia ION as well as AMD's own FUZION E350 is a testament to this.

I maintain that so long as you build a FM1 system in a cut price fashion, it represents very good value for money. However as I've said in the review, you've got to be bonkers to spend big £££ on a A75 FM1 board.Quote
