[Puget Systems] AMD A10-7850K Performance Review - Page 2

Good point, AMD needs to get their butts off the ground and start working, they will fail badly otherwise.

Ok so dump the intel chip out of the picture and just compare the Kaveri and Richland chips. Not much of a difference between the two. 5-10% for all the promising. The last chip I had from AMD that I was impressed with was the 1055t that I bought second hand on OCN. My FX 8320 was a nice chip at 5.0ghz too.

Sorry I am rambling, I just was really hoping to go back AMD, but with a Microcenter next to me I guess not frown.gif

I just hope people don't start hating me for just reporting whats available right now. I will be adding new reviews as they keep coming.

So the question now is if Kaveri is worth anything. Based on these and other similar benchmarks I would say it's only pro over Richland is the support for HSA and Mantle (with IGP). At $40 more than the 6800k I don't see a good reason to buy the 7850k.

Sure LibreOffice supports HSA to some degree but who would choose that over Microsoft Office?

Sometimes it's better to improve on existing technologies than to attempt to re-invent the wheel in the hopes that everyone will adopt it.

That's still a very small group of people.

In an attempt to stay positive about this product launch (sort of difficult looking at these results), I do wonder if Kaveri can hit clocks on the CPU and GPU like richland (or better), and perhaps push into the upper DDR3 speed territory (3000?). If so then there's more headroom to improve into with overclocking here, so this may prove to be better once overclocked by a more respectable margin. Wish they had done power consumption comparisons, as that would offer some insight into whether or not they delivered on the compute efficiency improvements or not.

Considering the fact that the same GPU architecture is currently packaged and sold with factory clocked speeds of up to ~1.1ghz (near 1.2ghz boost on some products), and this thing is only churning 720mhz base.... there's "theoretically" up to ~60% improvement potential in shader bound workloads.


I am often frustrated by the position that a benchmark is somehow not "valid" because it doesn't meet the criteria of the person criticizing it. Especially when the position is brought up in a situation where the benchmark reflects real world workloads regardless.
1. The real world is not necessarily optimized for AMD, why should the benchmarks be? Why is it everyone else's responsibility to "fix" the performance of a non-mainstream product? A benchmark that is heavily optimized for an AMD chip isn't likely to translate to accurate real world performance comparisons. I see more similarities than differences in results between "benchmark-software" and "application-benchmarks," which tells me that most "benchmark-software" is actually better than folks give it credit for.
2. There are very raw hardware level benchmarks that simply look at cache and memory performance, latency, bandwidth, etc, that wind up being very telling about how a CPU performs. Piledriver has poor cache latency performance and memory controller performance compared to the last 3 generations of Intel chips. There is no way to "optimize" or "compile" software that depends on these performance traits in such a way to overcome these failings. A chip with "bad" performance in these raw cache performance traits can't perform better than a chip with "good" performance in these traits, it simply isn't possible.

To bottom line it: When people don't like the results of the benchmarks, they look for ways to discredit them.


PS: I have never paid for office. Been using OpenOffice (or some variant of it) for as long as I can remember.

No HSA support means 10% improvements isn't out of the question...

also the Stilt said A88X is weaker, we see that in this bench's memory results I think
Quote:
The A88X chipset offers nothing new compared to A85X.
In fact it is worse than it's predecessor.

A88X has an upgraded AHCI / RAID controller which makes it unable (as it currently appears) to run over 106MHz BCLK while AHCI is enabled. Personally I would rather see the top tier FM2+ motherboard using A85X FCH instead of the A88X.

20-30% claimed IPC increase with 10% lower clock speeds means at least 10% performance increase in everything non-HSA related. HSA supported software should see gains far greater than 10%, I would say 40% at minimum.
