AMD Launches The A10-7800, The 65 Watt Kaveri

[Ericg]

hmm I just dont understand the kaveri I guess.

In my mind u need a slow pc kabini for normal tasks but gaming, and a fast cpu for gaming.

Then there is another task thats virtualisation. does hsa bring advantages in virtualisation I doubt it.

I get amd has Mantle for gaming, but that is not amd cpu specific so its no kaveri advantage.

If at least hsa would be a real thing that basicly every app uses very hard, u could argue by libreoffice heavy users or something with very big tables or something like that.

So I just dont get why anybody should buy a kaveri, except "its good enough". But then again in most cases thats true for a kabini too, but less expensive and less power costs.


Maybe for lowend players. or to get a good mix of good aplication speed and somewhat ok gaming speed.

I am maybe to specialise thinker. I guess u have less cables when u have one pc for everything. and less problems with monitorswitching... for lazy people or people or people that want only one box on the table or dont use notebooks or only a desktop replacement, maybe its ok thing.

Kaveri, when paired with 2133mhz RAM, gave me more than acceptable gaming speeds (40+ Fps on High in Borderlands 2, 60+ FPS on High / Medium in everything else so far), it reduced the power draw of my rig, and it reduced the heat I had to worry about from running a dedicated graphics card. Also it allowed me to wait and see what AMD has planned for GCN 2.0 next year / switch up to Carrizo if I so deem it.

I'm a college student who built their own custom rig on a $600 budget and who needed good cross-platform support between Windows 7 and Linux, could I have gone for a hand-picked Intel+AMD build? Sure, I had one in mind. But I am very curious about GCN 2.0 / Carrizo, and if they are something amazing then I didn't want to toss multiple items I had already bought.

The WORST case next year is that Carrizo is awesome & I want one: I take the 7850K out of my current desktop, drop in Carrizo, and I put Kaveri into the media server / NAS / Web server I'm planning, saving myself from having to buy a CPU.



My point is: Its based off of everyones unique computer needs.

What is so special about single-threaded performance? Does single-threaded performance beat the snot out of multi-threaded performance?

Why are people making such a big deal out of single-threaded performance?

Probably because many utility apps make lousy use of additional cores. In gaming it's even worse.

Just saying. Please don't bash me. I think APU is a great line of products

1) They are NOT low performing CPU cores. They are quite up there with intel. They just don't show well on standard "intel-favored" compilers, and sure, they don't quite keep up with an intel chip costing a THOUSAND $ MORE (which might get a whopping 1% improvement... big deal)

Which Intel chip costs a thousand dollars more than an AMD chip and only shows itself being 1% faster?

borderlands is not very gpu dependend and also not cpu dependend I guess. That there are nearly no interesting games recently is shurly a problem or I get old or games was always bad and I just now notice it but there are some games that need more cpu and more gpu power, more gpu power cant hurt on nearly every game. more cpu power on some games, like battlefield or planetside 2...

I probably could have kept my fx4100 but I though 50 euro for a upgrade to a fx6300 and because I bought a new cooler and had to put the motherboard out of the case anyway I did go for it, thought of a 200 euro xenon that would be like a core i7, 8 logical cores... aka ht or what... but that would be way to big right now, and to have a gpu that bottlenecks not that cpu would be a dualgpu card or something like that...

But even my fx4100 (costs at ebay 30 euros) + my hd5850 (maybe 50-70 euros at ebay)would brought way more fps or allow way better settings than a kaveri.

Maybe I miss the point is it very good at fps / power consumption? So that u get most of your power bill?

it reduced the power draw of my rig, and it reduced the heat I had to worry about from running a dedicated graphics card. Also it allowed me to wait and see what AMD has planned for GCN 2.0 next year / switch up to Carrizo if I so deem it.

there are also low power grafics cards, but they have their own memory and are faster because of that.

I'm a college student who built their own custom rig on a $600 budget and who needed good cross-platform support between Windows 7 and Linux, could I have gone for a hand-picked Intel+AMD build? Sure, I had one in mind. But I am very curious about GCN 2.0 / Carrizo, and if they are something amazing then I didn't want to toss multiple items I had already bought.

why do u need good cross platform, I guess some guys buy kaveri because of that, still even I belive all numbers about linux adoption rate for dualboot systems are way to low and maybe 10% of the users have it already, it should be not the most, then again amd has maybe only 20% market share, but many linuxers even I dont understand buy nvidia cards for linux so this 10% are not all amd gpu users.

But in reality that is for me no real argument, or at least only in some cases, Dualboot is a compromise, if u use 90% of the time the one os maybe, but whenever I tried that, I got stuck in windows, because there I can surf do most stuff and gaming, while in linux I could only do everything except gaming, the programms u only get under linux are very few.

and to have to boot around is just a to big dealbreaker, ok if u use some external devices like tv or full stereo receiver, u get that right, I drive everthing musik videos... over the pc and looking a few time a day a minute onto a black screen with some random text and cant do nothing is no option.

And I think I am maybe special with having 2 desktop systems one kabini and one bulldozer for only gaming with synergy to use mouse on both systems 2 monitors with one switching between windows and 2nd monitor for the kabini system ist maybe special but most use to his normal pc also a laptop. So why not put linux on the laptop where u cant play anyway and put windows only on the ohter pc.

Ok I am no real desktopreplacement notebook guy, for the same price u can get a low power notebook with long runtime + a good desktop rig.

The WORST case next year is that Carrizo is awesome & I want one: I take the 7850K out of my current desktop, drop in Carrizo, and I put Kaveri into the media server / NAS / Web server I'm planning, saving myself from having to buy a CPU.

The worst case is that carrizo brings no big advantages und u have to stay on that plattform for several years or change to intel. or karrizo only brings big advantages if u use him with ddr4 where I guess u would need another motherboard so u have to replace everything too.

But I think the biggest advantage of kaveri is the hsa feature, without it, even a i3 should maybe be better. aka needs less power and is faster ( a good i3).

so kaveri is for people using blender gimp and libreoffice, and that only potentialy because till now the software only gains in some rare cases the advantages? And maybe for people that want to use one pc only and dualboot much. yes its ok... that just is not my usecase

For me kabini and co is perfect, really low power and fast enough in my opinion for everything but gaming, I even drived a E350 for some years so a fast 2,5ghz kabini quadcore should be enough for everything.

But again I am no hardcore blender / libreoffice / gimp user.

But the ads go more in direction of gaming, that I find funny, because there its raw cpu and gpu power and there intel is better.

Pointing to specific intel chips would be pointless because they pretty much all qualify.

I can count on two fingers the number of Intel chips that are in the thousand-dollar category.

And even fewer Intel chips that are only 1% more powerful than what AMD offers.


So I think it's much more likely that once again you were talking out of your ass.

It's okay to be loyal to AMD for some emotional reason or whatever, but let's not mince facts here. Intel has far better offerings up and down the product line.

Intel better? Depends on the job

CPU pricing at a computer store seems to be set by what they are worth to gamers, but what if gaming isn't what you are buying the chip for? I know bulldozer is reported to suck for gaming and single-threaded, but for video editing it is nearly 50% faster than my older Phenom II x4 chips were. Published benchmarks have shown AMD performance in libx264 (my main load) to be comparable to Intel chips of same year of release selling for about $100 more. Due to the fact that this CPU is not so hot for anything else (except possibly server use), if I kill mine I can get another 8-core for as little as $140-until the lack of demand shuts down the FX line. Wonder what they will then trade for on E-bay? Keep talking trash, you will save me money if electromigration kills my main chip...

First off just what 'utility' software do you speak of? Compilers aren't, spreadsheets can benefit from being massively parallelized, Encoding/Decoding usually is taken care of by dedicated hardware, FRAPS prefers to run on an octocore, for a virus scanner you want more cores so that virus scanner's threads don't interfere with the other threads running on the system

The rest of your office suite products don't care about performance, IDEs don't care about performance, web browsers aren't really that performance sensitive (nor should they be), game client software (steam, desura, etc) doesn't care, your file browser doesn't care,

etc...

Also the idea that games make poor use of additional cores is a myth that's only really true of bad console ports.. There is a reason that FRAPS likes more cores

Why does the picture graph say the 7850 can use DDR3-2400, but the wikipedia page says only DDR3-2133? Which one is correct?..

Here is the wikipedia link: https://en.wikipedia.org/wiki/List_o...14.2C_28_nm.29

Maybe both . 7850 is not just 7850 but has K letter, so that is 7850K. K means i think Kali, which means black in indian language, so it is overclockable procesor (unlocked multiplier & Co.) and it comes in black package. So if you run that in stock speed DDR3-2133 is recommended, if you want to overclock it then you should know that DDR3-2400 when you do OC is also supported.

7800 is just that - no K there, but insted of that it is power optimized and comes in white package .
