Thanks to The Overclockerz Store for supplying us with the ABIT KT7-RAID and the Duron cpu.


Some time ago Ryan from The Overclockerz Store asked me if I was interested in testing one of
their latest and most successful combo’s containing one of the best motherboards available, the
ABIT KT7 RAID and a Duron cpu clocked at 1GHz.

Off course I took the offer and a week later the material arrived at my doorstep. The cpu
was wrapped in foil to prevent it from being damaged on its long journey towards me. After I
unpacked everything I was ready to install it and start testing.


- 600MHz stock speed

- 6x mulitplier (unlocked to whatever you want)

- 64kB on-die L2 cache memory

- 462-pin socket A design

- 1.6v core voltage

The Duron isn’t all that different from AMD’s TBird cpu. Actually the only difference between
both cpu’s is the amount of L2 cache memory. The TBird features 256kB on-die cache memory whereas
the Duron only carries 64kB of L2 memory, also at full core speed.

As you can see in this screenshot taken from Wcpu (can be found at H-Oda)this Duron is manufactored with the model 3 core. This means that one day the Duron CAN have 128kB of L2 cache instead of the 64kB
we see now. My guess is that AMD is holding this trick up their sleeve in case Intel adjusts it’s Celeron to be faster then the Duron. Then AMD pulls out this joker and it’s ‘bye bye Intel’.

Below is a picture that explains what all those numbers on the cpu core are telling us. Thanks to Hard|OCP for the picture!

As you can see default voltage is 1.6v which is the same as the Celerimine cpu (starting at 600MHz that is). It also shows us that we have 64kB L2 cache and that the cpu is manufactored in the socket A format.

Some people say there is a difference between a blueish core and a greenish core. AMD builds some of its cpu’s with copper interconnects, others are built with aluminium interconnects. The cpu’s built in Texas are made out of alu interconnects, the cpu’s made in Dresden are made with copper interconnects.
Cpu’s from Texas have a green tint on the core, cpu’s from Dresden have a blue/purple tint. Although AMD is claiming they are not (yet) manufactoring any Durons
with copper interconnects, mine (which actually is a Duron 600) has a blueish tint on it. Normally AMD only uses copper interconnects on 1GHz TBirds and up, but since these are not sold as much as
cheaper TBrid or Durons, it is possible they just remark these cpu’s. I also have a Duron 800 sitting in the testlab with a greenish core, and I can not overclock as well as the Duron 600 with the blue core.
I don’t know if these statements are true, but I can confirm a blue core overclocks better then a green one (for me anyway) so if you can chose which one you’ll buy, I suggest
you take to blue one :).

Installation of this beast …

Simplicity rules! Just unlock the cpu with your pencil, put it in the socket on the motherboard (we used the KT7 RAID), put some
thermal grease on it and put the cooler on it. As we all know heat is the worst enemy of overclocking, I have chosen to use the Globalwin FOP38 to cool this freaking speed monster down.
After we installed the cpu into our testbed we were ready to do some serious benchmarking and overclocking ;).


Since The Overclockerz Store pretested this cpu at 1000MHz, I already knew it would be good for a GHz of gaming power. Still I was interested to see if I would be able to get it even higher.

I managed to get it stable at 1040MHz / 1.85v with a multiplier of 10x and a fsb of 104. But I have chosen ro run the cpu at 9.5x107MHz which gives me 1035MHz which is indeed a tad slower BUT my ram is running 7MHZ faster this way resulting in better memory performance.

Ok the overclocking part is done, now lets head over to the benchmarking shall we?

Benchmarking – Duron vs. TBird

Test system:


- Duron 600 @ 1035MHz / TBird @ 1035MHz

- 2 x 128MB Mushkin High Performance RAM cas 2-2-2

- Hercules Geforce GTS 64MB

- IBM 35GB 7200rpm UDMA100 hdd

I wanted to see how fast this cpu was in games, but also in applications. That’s why I have decided to run a bit more benchmarks and explain them a bit better. Because most people wonder if there are a lot of differences between the TBird and the Duron, we’ll test both of these cpu’s.

First benchmark we’ll show is Sisoft’s Sandra, one of the most used bench suites out there …

Here you can see that the Duron is a bit slower then the TBird at 1GHz, but it is overtaking the 1GHz PIII all the way.

The TBird isn’t bad at all if you ask me.

Again we see the Duron ovetaking the 1GHZ PIII and getting beaten by a small margin by the TBird.

Also here the TBird is faster but it has more L2 cache memory

In the memory scores the Duron is killing all contenders!

The Duron kicks the TBird here, but its memory is running a bit faster too.

As you can see from these tests, AMD is kicking Intel’s arse all the way. It is incredible to see AMD’s lowbudget cpu outperform
Intel’s top model. The Duron also manages to come real close to the TBird. The memory scores on these AMD’s are the best I ever saw!

Secondly we’ll use CPU Mark 99 and FPU Mark 99 to show this Duron’s strength.

Not bad huh?

Outstanding no?

Not much to say about these numbers … they just speak for themselves I believe. Unfortunately we had no numbers on the TBrid since we have only implemented these new benchmarks starting with this review.

Next benchmark we’ll run on the cpu is 3D Mark 2000, a suite that is very good at showing game performance.

Ths is a new personal record for me!.

3D Mark shows us how good the cpu will perform in games. That’s why I used the default benchmark with a resolution of 1024×768 and a colordepth of 16-bit. I did not wanted the videocard to be bottleneck of the tests. I can not compare these results with the ones I got from the TBird since I am using DirectX 8 and the new 7.17 Detonator drivers which gave me a nice bump in speed!

The last test we’ll do is another gaming test: Q3 Arena

We only ran one test: demo 1 at 640×480 / 16-bit to make sure the videocard is not being a bottleneck.

We got 121.7fps in this modus which is pretty nice no?
All settings were maxed out and sound was enabled to create a real gaming environment.


AMD has designed one great cpu, that’s for sure! The Overclockerz Store has also noticed that and they took this oppurtunity to present us one great combo for the gamers between us. I don’t think the TBird is worth the extra cost if you look at the small advantage it gives us in real life use. So if you are lookig for a great combo at a really good price, head over to the OCZ and buy it! They also have other interesting combo’s available.
