My home laptop has a Core i7 2860qm (quad core 2.5 GHz, 8MB L3 cache) and 16GB of RAM.  Performance in Dragon Medical 10.1 is outstanding.

At work I have been using a Core 2 Duo T9300 (dual core 2.5GHz, 6MB L2 cache) with 4GB RAM, and performance has been okay with Dragon Medical 10.1, but my home laptop has me wanting more at work.

I happen to have two "extra" desktops lying around, and I was wondering which one would make a better replacement for my work laptop.  Which one of these would perform better with Dragon Medical 10.1?

Candidate A: Core 2 Quad Q9400 (Release date: 2008, quad core 2.66 GHz, 6MB L2 cache) 4GB RAM

Candidate B: Core i3-2130 (Release date: 2011, dual core 2.40 GHz, 3MB L3 cache), 6GB RAM

I realize that neither of these candidates will match my home laptop's performance, but I'm guessing that both will outperform my current work laptop.  Candidate A has faster clockspeed, more cores, and more total L2/3 cache, while Candidate B is newer (Sandy Bridge) and has a bit more RAM.  Which one will work better with Dragon Medical 10.1?  I am not going to be using Dragon 11 or 11.5, so please answer only in terms of DNS 10.1 (on Windows 7 Professional 64-bit).

Amin,

First, you have the technical specifications for these two desktops slightly incorrect.

Candidate A is a Core2™ Quad that predates the Core™ i processors, has no hyperthreading, does not have any L3 cache (only L2 cache), and wouldn't be as well suited for DNS 10.1 Medical as Candidate B.

Candidate B is a second-generation Core™ i processor (Sandy Bridge), does have hyperthreading, which allows it to perform as if it had four cores instead of two, does have at least 3 MB of L3 cache, and you got the processor speed wrong because it's not 2.4 GHz it's 3.4 GHz. The only thing it's lacking is Turbo Boost, but processor speed is not as critical as L2 cache vs. L3 cache, total amount of RAM, and the overall processor technology. Note that Candidate A does not have Turbo Boost either, so it's actually slower than the Core™ i3 in terms of processor speed. Also, in terms of relative cores, Candidate B is actually a better four core equivalent system because of hyperthreading, which gives it four threads that technically act like it has an additional 2 cores, and L3 cache that Candidate A does not have. Remember that L3 cache can be shared across all cores in any multiple core processor, whereas L2 cache is dedicated cache and can only be used by the core to which it is connected. That is, if core one is being used by DNS and the information that would be useful in the given process is only available in the L2 cache for core four, then it's inaccessible to the CPU and the CPU will have to go out to RAM to get the information you, which slows the performance of DNS because RAM is many hundreds of times slower than CPU cache.

However, when comparing the two relative to DNS 10.1 Medical, remember that DNS 10.1 doesn't use multithreading/multicore processing (i.e., it only uses BestMatch III and a single core for processing dictation) and is less resource intensive than DNS 11-11.5. So, DNS 10.1 Medical would perform better (faster) on your Candidate B system than it will on Candidate A, and likely significantly better. In fact, you might be surprised to find that Candidate B performs almost as well as your Core™ i7 2860QM with DNS 10.1, if not almost equally as well. If you're using DMPE or DNS 11-11.5 Premium, Professional, or Legal, then you would see a difference your Core™ i7 2860QM and Candidate B.

Thanks, Chuck.  Candidate B it is!

Chuck was right, the Core i3 desktop, which I upgraded to 8GB RAM, performs nearly as well as my Core i7 laptop when it comes to DNS 10.1.  Very pleased!

10.1 provices 64-bit operating system support, running on Windows Vista 64-bit operating systems. Does not support Windows XP 64-bit operations systems.
