New AMD Phenom X3 Vs. Phenom X4

Phenom X3 With Three Cores

When the Phenom processor was introduced, AMD chose not to use the "X4" extension as part of the model name. All Phenom models, without exception, had four processor cores and thus there was no need for the extension. Today’s introduction of the new Phenom processors with one CPU core less, makes it necessary to add an extension to the product name in order to ensure that they can be differentiated, thus AMD officially introduced the extensions X4 and X3 for all Phenom processors. According to AMD, many customers have expressed the desire for this change.

The Phenom X3 will only be available with B3 stepping without TLB error to end customers who purchase the processor as a tray or in the box pack.

For OEMs (Original Equipment Manufacturers) who produce complete PCs, the Phenom X3 model is available with the older and faulty B2 stepping. AMD considers it important that end customers are only able to access a fault-free processor in future.

The tri-core Phenom X3 is technically identical to the quad-core Phenom X4. Each individual CPU core has a 512 kB L2 cache and all three cores are connected to a 2 MB L3 cache. Like all of the Phenom X4 processors, the X3 is made using 65 nm process technology.

The code name has simply been changed from Barcelona to Toliman.

AMD is introducing three new Phenom X3 models:

- Phenom X3 8750 (2.40 GHz)
- Phenom X3 8650 (2.30 GHz)
- Phenom X3 8450 (2.10 GHz)

Since the new models do not contain the TLB bug, they contain a 50 at the end of the product name.

AMD does not yet intend introducing a Black Edition with a freely selectable multiplier.

In order to run the Phenom X3, AMD suggests installing the latest Bios version on the board. The tests showed that the 790FX boards from Asus, Gigabyte and MSI started with no problems. All programs used in the course of benchmark testing were able to complete their work with the Phenom X3.

The one exception was Sandra by Sisoft. The program could be started, but showed no reaction when executing the benchmark tests. Since this is a synthetic benchmark utility, this can be ignored, particularly as this behavior occurs frequently when using Sandra on new processors from both Intel and AMD.
