AMD A-Series A4-3300M



The AMD A4-3300M (Codename Llano) is a dual-core processor for entry level laptops. It is part of the Fusion family of APUs (=Accelerated Processing Units) and features an integrated Radeon HD 6480G graphics card. The processor core is clocked at 1.9 GHz base clock speed and is able to automatically overclock up to 2.5 GHz (TurboCore, depending on temperature and used cores). The processor core is based on the Husky familiy 12h. Compared to the older Phenom II mobile processors, the Husky core is very similar but features an additional hardware divider. However, the performance per clock should be similar to the old Turion II, Athlon II, Phenom II mobile processors (as the Llano APU they did not feature a Level 3 cache).The performance of the processor part should be comparable to a previous AMD Athlon II M320. Due to TurboCore the single threaded performance should be slightly better and the multithreaded slightly slower. Therefore, the performance is clearly worse than similar clocked Sandy Bridge based processors (e.g. Core i3-2310M).The Llano APUs feature an integrated DirectX 11 capable graphics card with a maximum of 400 cores. The AMD Radeon HD 6480G called version in the A4-Series however offers only 240 cores at 444MHz. It has no dedicated memory and also is not able to use the integrated cache (in difference to the Intel HD 3000). Furthermore the APU also features an integrated UVD3 video processor to fully decode most used HD videos (like H.264, VC-1, MPEG4).The A4-3300M also features an integrated dual-channel memory controller with support for DDR3(L)-1333 memory and a PCIe 2.0 controller.The TDP of 35 Watt for the APU (including graphics card and memory controller) makes it best suited for 14 to 15-inch laptops.

Windows 7 Ultimate 64 bit

SuperPi mod 1.5 1M Result: 30 seconds

Furmark Test: Open Furmark and set to 400:300. Uncheck ALL checkboxes. Click the Burn In Test. Result: 147 frames in 20 seconds.

This sounds like its not really all that bad. After all, the Nvidia 6200 in my other PC only gets 20 frames in 30 seconds. But its when you run Furmark that you see what the real problem with this chip is. When I click and drag the Furmark window as the test is running, there is this awful lag. It is very bad and very annoying. Installing windows and all the programs I usually install was very annoying. There were times when it simply froze for 5-15 seconds. Very aggravating. There is something seriously wrong (or underpowered about this chip). I just installed W7 on an E6600 system last week, and it flew. It didnt freeze up all the time like this system.

I thought that maybe I wasnt running in dual channel mode. So I moved my dimms around and reran Furmark. New Result: 80 frames in 20 seconds!! Now that is really really bad. So I put it back in dual channel mode.

Next up, overclocking. Set multiplier to 35 (3.5GHz), and was not surprised when I saw super ip 1M was still at 30 seconds. We all know the multi doesnt work but I had to try anyway.

Next I set the RAM to 1600. No dice. I would not post! This is sad because this is DDR-1600 ram. I loosened all the timing to even worse than SPD and not only would it not post, but I had to clear cmos just to get it to revert. So here I have this expensive board and some of the best budget ram you can buy, and no dice. Cant go faster than 1333.

I installed a ZOTAC ION PCIe X1 card ( http://www.newegg.com/Product/Produc...82E16814500164 ) just for comparison. Right away I'm having a problem very similar to the updating problem... it is taking forever to do things that should go relatively quickly. I literally just installed this card in my E6600 system and it took 3 minutes. On this A4-3300 system it took 12 minutes, including 7 minutes stuck on the "Preparing to shut down your computer" screen. What kind of two-bit crap is that?

Anyway I got the ZOTAC ION installed. I ran Furmark. Same settings, 400:300 with all boxes unchecked. Results: 154 frames in 20 seconds. It still lags quite a bit when moving the Furmark window around. But it is definitely more fluid. Almost bearable.

I removed the Zotac card and went back to onboard video. In the bios I clicked "load optimized defaults". Now Furmark at 400:300 with zero checked boxes gives me 178 frames in 20 seconds. This is kind of odd. I reran and it gets only 90. Sometimes 90. Sometimes 180. Sometimes 130. This is really strange. Disabled CnQ. Same odd results.

I installed league of legends just to see if it can run that game on max settings at 1080p. Based on what I've seen so far I am preparing to be disappointed. LoL Results: at 1440x900, windowed, all medium settings: 18-24 fps. Plays pretty crappy. I couldnt do it regularly I know that. But it is close to playable.
