AMD Athlon X2 7850 vs. Intel Pentium E5300: Choosing the Best $70 CPU

DivX 8.5.3 with Xmpeg 5.0.3
Our DivX test is the same DivX / XMpeg 5.03 test we've run for the past few years now, the 1080p source file is encoded using the unconstrained DivX profile, quality/performance is set balanced at 5 and enhanced multithreading is enabled:
The original Phenom was significantly weaker than Intel’s Core 2 at DivX encoding, thus the Athlon X2 vs. Pentium comparison here isn’t very favorable for AMD. The E5300 is 11% faster than the 7850 here. Even the E5200 is a better choice for DivX encoding.
x264 HD Video Encoding Performance
Graysky's x264 HD test uses the publicly available x264 codec (open source alternative to H.264) to encode a 4Mbps 720p MPEG-2 source. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.
The x264 HD encode test is slightly different depending on what pass you look at. The first pass of the x264 HD encode actually has a number of unaligned loads, which penalizes Intel’s Core architecture - something fixed in Nehalem. The second and more CPU intensive pass is where Intel sees a 7.4% performance advantage over AMD. Despite the small advantage in the first pass of the encode, the win goes to Intel for a larger and more meaningful advantage in the second pass.
Windows Media Encoder 9 x64 Advanced Profile
In order to be codec agnostic we've got a Windows Media Encoder benchmark looking at the same sort of thing we've been doing in the DivX and x264 tests, but using WME instead.
Our final pure encode test once again has the E5300 ahead of the Athlon X2 7850, but by only a 3.4% margin.

I don't agree about intel being the clear choice, (enthusiast or otherwise)You have to factor in boards being used to. Chances are most that are looking for a bottom feeder budget build will be using integrated chipsets. The 780g/v brings so much more to the table over what we currently get from intel offerings..
That was a key sticking point for me.. and I think it really makes the choice a hard one to make unless your brand loyal, or a overclocker looking for a cheap cpu based around a competent setup.

Depends on what you need, I went for a 650i motherboard with a single PCIe slot for an 8600GTS ( the 2ghz ram actually seems to help with the 128-bit bus). It was $40, and you can get that deal yourself.I doubt for $140 you can beat a 3.3-3.4 ghz core2 with an 8600GTS.

Yeah, that's what I was thinking.Zaitsev - Tuesday, April 28, 2009 - link
I was hoping to see a few words on OCing as well. I mean, having two cores disabled should yield some more headroom than the quad core parts, right?Anand Lal Shimpi - Tuesday, April 28, 2009 - link
I didn't have time to test overclocking for this article but if there's enough demand we can definitely look at how the two compare. The E5300 has a good amount of headroom thanks to its 45nm process, I'd expect the standings to remain the same if not widen in favor of Intel.Take care,
Anand

Please do OC the chip ...crimson117 - Tuesday, April 28, 2009 - link
OC results on these two budget CPUs would be great - but it'd be best if it were normalized somehow...1. Same price-class motherboards, around $100 or less to match the low-cost CPUs
2. Same exact ram modules
3. Same heatsink, or limit it to included stock heatsinks
, and re-run just a few choice benchmarks.
Would make for a great blog post :)

While you're at it, you should unlock the other 2 cores as well...http://www.atomicmpc.com.au/News/143621,amd-x2s-ar...">http://www.atomicmpc.com.au/News/143621,amd-x2s-ar...

I've read dozens of articles and posts claiming that you can unlock the extra core(s) in the new X2's and X3's, and exactly ZERO telling how to actually do it. Is this some sort of urban legend?ssj4Gogeta - Tuesday, April 28, 2009 - link
Yes we'd definitely like to see OC results. I'm sure after OC'ing both chips to their max. gaming performance will be significantly better on the Intel part too.
