AMD A10-5800K & A8-5600K Review: Trinity on the Desktop, Part 2
by Anand Lal Shimpi on October 2, 2012 1:45 AM ESTPower Consumption
Intel has a full process node advantage when you compare Ivy Bridge and Trinity, as a result of that plus an architectural efficiency advantage you just get much better power consumption from the Core i3 than you do with Trinity. Idle power is very good but under heavy CPU load Trinity consumes considerably more power. You're basically looking at quad-core Ivy Bridge levels of power usage under load but performance closer to that of a dual-core Ivy Bridge. AMD really needs a lot of design level efficiency improvements to get power consumption under control. Compared to Llano, Trinity is a bit more efficient it seems so there's an actual improvement there.
Of course on the processor graphics side the story is much closer with Trinity being a bit more power hungry than Ivy Bridge, but not nearly by this margin.

It's good to finally see pricing on Trinity.Looks like AMD is still competitive at lower price points for Video transcoding performance, which is good news for me and others who's highest CPU workloads are mostly video editing.
But even for gaming the A10-5800/K doesn't look too bad for $122 chips.
Glad to see it isn't quite "Bulldozer" all over again. I need to build a new system for Windows 8 and Trinity looks promising for a budget to mid range build.

Big deal...Just look at pg 2, the single threaded performance of the A10 is lower than a friggin Pentium G850
Pg 3 Sysmark, only slightly ahead of the Pentium even with 2 additional Integer cores
I wish Anand had included the Pentium G850 power comparison as well though at 65W vs 100W TDP we can be sure which way that will swing...
And the G850 costs a little more than HALF the A10 suggested price... That puts a $70 saving towards a discrete graphics card, which, as per pg 6 should result in a much better gaming performance as well...

It's also slower than an old Core 2 Quad Q6600 overclocked to 3.6ghz+ which was released in 2007 both in single threaded and multi-threaded tasks.However, what I would like to see is some under-volting tests to see how low they can go in terms of TDP as AMD has always been incredibly conservative (Even on the GPU side) with voltages, would be excellent in a Mini-ITX rig without the need for a dedicated GPU.

Really cool how the performance charts are NOT static.Ah, German technology. :)

I think there is very little need for raw single-threaded performance increases in consumer-level "general computation" processors (e.g. few-core x86 processors). So who cares if we don't have a second intel? What we do need are better ways of extracting performance from multiple cores, and from the massively parallel architectures found in GPUs. Part of the equation is ensuring that these two paradigms are pervasive, and therefore,https://audiomanagerapp.wordpress.com/2017/10/11/a... from a big-picture point-of-view, AMD really *is* pushing things forward with TrinityB3an - Tuesday, October 2, 2012 - link
Trinity truly is embarrassingly slow. I think it should be even cheaper for this performance level. And it's also disappointing that Intel have no performance competition AT ALL from AMD. We need this for some real progression to be made in desktop CPU's and also drive prices down at the high end.IKeelU - Tuesday, October 2, 2012 - link
What kind of progress are you talking about? Power efficiency? Raw general computing performance? Progress comes in many forms.I think there is very little need for raw single-threaded performance increases in consumer-level "general computation" processors (e.g. few-core x86 processors). So who cares if we don't have a second intel? What we do need are better ways of extracting performance from multiple cores, and from the massively parallel architectures found in GPUs.

AMD's progress is about 2 years behind. While this is somewhat intel's fault by illegal competitive practices which in turn kept AMD from profiting as much as they could have during the Athlon64~X2 era.AMD has done a lot of things wrong and would take at least 2 years to sort out... if ever. FM2 is no better than FM1 and not cross compatible. Neither is compatible with Socket AM3 and nothing AMD has on the market even supports PCIe 3.0.
Compared to buying an intel i3-something system, in which you can upgrade to an i7-something easily. AMD has a mess on their hands and I suspect part of their performance problems could also be rooted in their chipsets. (Across the board, the performance hits a wall). Yeah, for a notebook - the powerful GPU part comes into play. And both intel i3 and Trinity is more than powerful enough for MOST people. hell, I'm still running on a Q6600 at 2.4Ghz and it does quite well (going i5-3570 this weekend)... But for those who want their money's worth when performance counts, AMD is not in the game.
The performance from AMD has to be consistent, and its not. The heat is not good along with the cheap fans they include that are noisy and should be replaced with a good $20~50 cooler. Meanwhile intel CPUs are running cooler and their fans are very quiet.
So as of today, in general - it costs more to get an AMD. I really want AMD to do well, I've sold lots of AMD systems in the past.

About PCIe 3.0, nobody needs that. 2.0 * 8 is enough to drive every card on the market with maybe 2% performance loss, which is within the error margin of every benchmark. To keep prices low, of course they're not going to add extra features that nobody needs. I think it's a smart move.Other than that, I agree. AMD hasn't been doing well price-performance wise the last two years. I have a Phenom II, and when they were released they were still competitive, for the price and the time, but the last two generations have seen no singlethreaded performance increase and cost about the same.
