Rohnin 10 Posted October 11, 2013 Did someone tried to put i7 quad into 6470b? I am afraid because in manual of this model are only dual core models. I want to make eGPU with this model but without i7 its pointless. Quote Share this post Link to post Share on other sites
kaladeth 15 Posted November 20, 2013 Hey Rohnin. I got curious as I've been considering a similar upgrade for my system, so I checked your manual again anyway:http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c03564727-1.pdfOn page 2 it does have an i7 quad in there:● Intel® Quad Core® i7-3540M 3.00-GHz processor (SC turbo up to 3.70-GHz; 1600- MHz FSB, 4.0-MB L3 cache, 35 W)Should work. Although why do you say an i7 is a requirement for an eGPU? Quote Share this post Link to post Share on other sites

kaladeth 15 Posted November 21, 2013 Oops you are right:ARK | Intel® CoreProbably a typo in the manual, and since there is no such thing as an i7-3540QM.Anyway should be plenty of power though right? Quote Share this post Link to post Share on other sites

We've had success retrofitting a i7-quad to a smaller Ivy Bridge 12.5" HP 2570P. It too was never factory shipped with one but it works and works well. See http://forum.techinferno.com/hp-business-class-notebooks/2537-12-5-hp-elitebook-2570p-owners-lounge.html#post33901Though you can see there it does help if the cooling subsystem is modified to deal with the higher temperatures in that small chassis. If that is a concern then consider installing a 35W i7-quad (i7-3612QM or i7-3632QM). Though the 6470B has a larger chassis and (presumably) bigger heatpipe so may be work fine with a 45W i7-quad?? 1 Quote Share this post Link to post Share on other sites
kaladeth 15 Posted November 23, 2013 Thanks Nando. That makes sense since it has twice the cores/threads.Now since the OP was asking in the context of an eGPU implementation, I grabbed a few samples from the leaderboards:DX9 15" Lenovo T520 i7-2860QM 2.5 16 GTX680@x1.2Opt 23749 226.8 Kuro-D & & QM67 EC Win7/64 12" Lenovo X220/T i5-2520M 2.5 8 GTX680@x1.2Opt 18078 144 arsenal243 rhx123 QM67 EC Win7/64 DX10 15" Lenovo T520 i7-2860QM 2.5 16 GTX680@x1.2Opt 29463 295.3 Kuro-D & & QM67 EC Win7/64 12" Lenovo X220/XT i5-2520M 2.5 8 GTX680@x1.2Opt 25847 197.4 arsenal243 rhx123 QM67 EC Win7/64 DX11 15" Lenovo T520 i7-2860QM 2.5 16 GTX680@x1.2Opt 8626 2441 Kuro-D & & QM67 EC Win7/64 12" Lenovo X220/T i5-2520M 2.5 8 GTX680@x1.2Opt 8585 2347 arsenal243 rhx123 QM67 EC Win7/64 So if I upgraded from an i5-2520M to a an i7-2860QM, from an eGPU perspective it seems a Quad can deliver ~31% improvement on DX9, ~14% on DX10, and <0.5% on DX11.Great advice on the heat/cooling consideration... will share back findings here when I get to Phase 2 (CPU upgrade) :).

kaladeth 15 Posted January 10, 2014 Just a quick update, the upgrade to a quad core CPU worked:http://forum.techinferno.com/diy-e-gpu-projects/2109-diy-egpu-experiences-%5Bversion-2-0%5D-254.html#post79680The performance gains were inline with expectations with a 34% improvement on DX 9, and a measly 0.6% on DX11 (Graphics Score).No mods to the heat sink were required. Temps are looking OK and should drop a bit further after the thermal paste settles. Quote Share this post Link to post Share on other sites
Kerio 3 Posted July 5, 2016 Excellent. I was looking for potential cpu's for upgrade in my HP probook 6470b (Other than the ones listed on HP website on product review) . So, glad that I found this thread. Is there any else who successfully replaced the cpu on 6470b? Please share the processor number. Quote Share this post Link to post Share on other sites
