AMD FX microprocessors, based on "Vishera" core, were available since last October. "Vishera" CPUs use the latest "Piledriver" architecture, and come with 2, 3 or 4 modules, which corresponds to 4, 6 or 8 cores. The chips also have up to 16 MB total cache, and support the latest instructions, including AVX and FMA3. So far AMD had 4 different retail models, and 2 other SKUs were shipped in computers only. Yesterday AMD refreshed FX family with two new products, FX-4350 and FX-6350.
AMD FX-4350 is a quad-core processor with 8 MB of level 3 cache. The CPU is clocked at 4.2 GHz, and has maximum boost frequency of 4.3 GHz. Compared to previously launched FX-4300 part, the FX-4350 increased base and Turbo Core frequencies by 400 and 300 MHz respectively, and also has twice larger L3 cache. The FX-4350 is a 125 Watt model, therefore it is less energy efficient than the FX-4300. The processor is priced at $122.
The FX-6350 has 6 CPU cores, clocked at 3.9 GHz, and up to 4.2 GHz when half of the cores are idle. Like the 4350, this microprocessor has 8 MB L3 cache and 125 Watt rating, so in essence it is faster and more power hungry version of its predecessor. Official price of the FX-6350 is $132. As a note, prior to this announcement, the FX-6350 was shipped for a few months in some HP desktop PCs, and now it will be available as a boxed processor.
Both CPUs fit into socket AM3+. The summary of their specifications is provided below:
|Model||Cores||Frequency||Turbo Frequency||L3 cache||TDP||Price|
|FX-4300||4||3.8 GHz||4 GHz||4 MB||95 Watt||$122|
|FX-4350||4||4.2 GHz||4.3 GHz||8 MB||125 Watt||$122|
|FX-6300||6||3.5 GHz||4.1 GHz||8 MB||95 Watt||$132|
|FX-6350||6||3.9 GHz||4.2 GHz||8 MB||125 Watt||$132|
