AMD Athlon X2 3800+ 

Released May, 2006
  • 2 GHz
  • Dual core
4.6 Out of 10

The 3800+ even bested a Pentium D 840EE in some benchmarks, which to me is astounding considering the price difference between the two, and while the 4800+ is without a doubt the top dog, the 3800+ at stock speeds and while overclocked shows itself to be a great choice.

If you're building a PC for gaming, an extra £30-50 spent on a Core 2 makes all the difference to your overall experience.

Reviews Word on the street for the AMD Athlon X2 3800+


8.0
If you're constructing a budget second PC though, a media centre system to pump HD video to your telly perhaps, then this is a quiet victory for AMD.

What People Are Saying Give it to me straight

Socket Type

Without a doubt, the 3800+ should be the first choice of any AMD fan on a budget (or anyone needing a new processor who is pinching pennies).
by Legit Reviews (Aug, 2005)
The Manchester core features fewer transistors (154M compared to the Toledo's 233.2M) and a smaller die size (147mm^ compared to the Toledo's 199mm^2), which also definitely gives it a far better thermal numbers than its siblings (89W as opposed to 110W).
by Legit Reviews (Aug, 2005)
The DFI board is using the 623-3 BIOS (latest official release), and the ASUS board is using the 4-22 BIOS (again, latest official release).
by Legit Reviews (Aug, 2005)

Socket

Using a minimum voltage increase (1.4V), setting the HTT to x4, and keeping the memory timings as tight as possible (1:1 @ 2-3-3-6), we'll judge the 3800+ in our benchmarks against the $1100 4800.

Keeping the multiplier the same while lowering the memory divider to 333MHz, and bumping the processor VCore up to 1.56V, I was able to hit 2.70GHz (270x10).
by Legit Reviews (Aug, 2005)
Now, we're going to leave the multiplier at its default setting (x10), set the HTT to x3, drop the memory divider to DDR333 (5:6), and raise the v-core to a point where stability is balanced with heat and performance.

Performance

Even so, this processor is an excellent choice for the enthusiast as well as the average user looking for performance on a budget.
by Legit Reviews (Sep, 2005)
While this processor came from AMD it is undoubtedly a top overclocker, please look at this as the high end you might achieve with your processor.
by Legit Reviews (Sep, 2005)
While great performers at stock speed, they really show their benefit when in the hands of a person who knows how to tweak and manipulate extra performance out of them.
by Legit Reviews (Aug, 2005)

Multicore

The consensus among this group seems to be that the IHS seats poorly on the processors cores.
by Legit Reviews (Sep, 2005)
While many appreciate the dual core performance at a budget price, we didn't have much time to really put Manchester core to the test for our overclocking readers.
by Legit Reviews (Sep, 2005)
While I am using water cooling for my test system, I was extremely impressed by a 700MHz overclock resulting in only a 2-3C rise in core temperature.
by Legit Reviews (Aug, 2005)

Overclocking

When overclocking, the best advice is really some old advice, isolate, then consolidate.
by Legit Reviews (Sep, 2005)
what this means is we will find the max overclock for the CPU, board, and memory individually, then consoldate them to find the best balance between each component in our system.
by Legit Reviews (Sep, 2005)
It seems that people who have removed the IHS report a significant drop in temperatures, which result in much higher overclocks.
