Damn it !!! How can I optimize my crap 2600K !?
You folks with AMD Phenom II at 3.6 GHz getting 16 khash/s on only 5 cores
Me with Intel 2600K at 4.2 GHz getting 9 khash/s on all 8 threads
Fuck Intel !
The 2600K doesn't have 8 real cores. It merely tricks the OS into thinking there are 2 cores for each real core to keep the CPU more efficiently loaded. Internally there are 4 actual cores. HT isn't a performance doubler because the CPU only has 4 physical cores not 8. Some applications perform slightly faster w/ HT. Some perform faster w/ HT off. All out database servers have HT turned off for example because we see higher throughput w/ HT turned off. The more the pipeline can be kept full the less advantage HT provides (eventually reducing performance when pipeline is continually full). Your comparison should be based on 4 cores not 8. The 2600K has 4 cores and will perform as 4 core processor when performance per thread is maxed out. Damn it ! Should have waited till Bulldozer with 8 REAL cores !!! FU Intel. |

Like THAT will help. Scrypt just sucks on Intel because of architecture just like Nvidia sucks at SHA256 etc. Use SC2. Probably a trojan in there too. |

I have a g6950 @ 3.8ghz doin nearly 3.7kh / core. Also, my i3 550 @ home @ 4ghz does 4kh/core Sure, still not as good as AMD but a lot closer then some of the posted results ive seen in the forum. |

Paying 2000 USD just for the CPU = EPIC ! Care to explain please with idiot proof instructions on 64bit linux Intel doesnt suck that much actually. I have a g6950 @ 3.8ghz doin nearly 3.7kh / core. Also, my i3 550 @ home @ 4ghz does 4kh/core
Sure, still not as good as AMD but a lot closer then some of the posted results ive seen in the forum. If I can get my 2600K to do 30 khash/s in total then it is worth it. Otherwise, no. AMD folks easily getting 34 khash/s with their junk chips. |

I think that Intel makes and markets them only for the very narrow niche where some "enterprise software" licenses are sold "per-socket". |

Which is exactly where we use them. You either pay intel or you pay Microsoft. Either way you are going to pay. Personally I prefer paying Intel. Too bad AMD DB performance is craptastic (well that is an exaggeration) or someday we may have a some AMD heavy iron. Then again if you are old enough you remember the saying "Nobody ever got fired buying IBM". Well today it is "Nobody ever got fired buying Intel". Not sure I would be willing to put my career on the line for a $20K+ AMD Server. |

AMD + Linux = you don't pay anyone You don't have to pay system admin's. Wow. Spoken like a 14 year old script kiddie with no concept of Total Cost of Ownership. Linux isn't free. Hate to break it to you but the cost of the OS is almost immaterial in the total lifecycle cost of most projects. So moving 140TB production and mission critical database to Linux platform would be free? Buying AMD servers, benchmarking them, and ensuring they can handle system load would be free (don't forget salary time spent doing so)? Converting couple million lines of T-SQL into PL-SQL or equivalent would be free? Putting my entire career on the line to save a couple thousand dollars (pennies in our IT budget) would be free? Firing our 24/7 windows/SQL Server support team, hiring and training Linux & Oracle admins would be free? Any system disruptions, delays, downtimes, and reduced performance on a 24/7 mission critical server would be free? In the real world companies really don't care about cost when it comes to mission critical hardware. Nobody looks to save a nickle if there is a risk to uptime. I sure as hell am not going to suggest a move from a stable known platform to a completely unknown platform just to save a couple grand. We tend to upgrade servers once every 4 years. Say we could save $500 per CPU x 8 CPU = $4000 every 4 years = $1000 annually. Not even 0.1% of IT budget. Ditching SQL Server would save us some coin but Oracle would cost even more. Windows Enterprise + SQL Server Datacenter COMBINED is cheaper than equivelent Oracle license. Moving our mission critical server to MySQL or PostgreSQL? I am not going to be the one pushing for it. Seems like you know your stuff. Well done. I was talking about home PCs though  |

Yeah, I do agree with you to a large extent. Intel has a much better control of their sales channel than the AMD. Intel is also better at publishing the utilities that allow for testing the CPU without disassembling the heatsinks. But historically Intel also had problems with the resellers of their whitebox server line. (I'm not sure if they are still making the whole servers, for sure they do whitebox motherboards that carry no prominent "Intel" mark.) In summary I'd say that the current version of this maxim would be: "You are much less likely to get fired for buying Intel than for buying AMD." By the way, on our tests IOMMU in 64-bit AMDs provides generally better performance than the comparable Intel technology. However we use custom-written database engines, not the obvious market leading ones. Overall I'm pretty much agnostic in this battle, we support Intel&AMD&others 32&64-bit, Intel Itanium, IBM POWER&z/Arch,Sun/Fujitsu/Oracle SPARC. We still have happy paying customers for Digital Alpha,HP PA/RISC, only the SGI MIPS machines dropped out of support. |

Do people trust tacotime to run binaries from him on their machines? (i suck at remembering people's names, so i dunno if i saw him elsewhere doing things that would've earned my trust)

(I dont always get new reply notifications, pls send a pm when you think it has happened) Wanna gimme some BTC/BCH for any or no reason? 1FmvtS66LFh6ycrXDwKRQTexGJw4UWiqDX The more you believe in Bitcoin, and the more you show you do to other people, the faster the real value will soar! |

If you got Intel then TBX sucks ! If you running Windows then TBX sucks ! They are too lazy to make optimizations so that Intel = AMD and Linux = Windows. Mine SC2 ! |
