Dual-core Atom 330 tested

Review: Cheap board does its job

 

About half a year ago, Intel introduced its Atom CPU series, and performance in some tasks was quite a disappointment for us. Intel made a step in the right direction introducing its first dual-core Atom CPU, as this one might actually have what it takes to get the right performance in this ultra-cheap market segment.

A year ago Intel had a huge stock of 945G chipset and thought: "What can we do with this junk?" - Atom was born. It is still laughable that Atom consumes up to 4W, while the chipset needs much more than that. Even the dual-core Atom 330 with its 8W TDP is still better than any 945G.

Concurrently, Intel decided to limit the feature-set on these boards, so there won't be any board with PCIe slots, which would enable any user to put a decent graphics-cards in the machine. Intel naturally doesn't like to compete with itself and Atom 330 is a desktop-only CPU that should make it to the cheapest, low-end machines. Intel won't let anyone use Dual-core Atom 330 in netbooks, which is a shame as a notebook with dual-core Atom would definitely be a great idea, but it would probably hurt Intel's existing dual-core notebook sales.

Atom 330 comes with the new Intel board is called D945GCLF2, which is the most basic board you can imagine. Intel still is in the year 1996, as the board features legacy ports such as COM and LPT, and they still did not manage to put a DVI connector on the board.

The most ridiculous decision Intel made is to put a 5500RPM fan on the Northbridge cooler. If you thought you can have a quiet machine because the CPU is passively cooled, you will be very disappointed. The system fan connector is badly placed, because there are many ITX cases which feature a fan on the right side, so there is a chance the fan-cable gets into the fan. Don't get confused because there is an ATX 2.2 power connector, it's not needed, any 20-pin ITX power-supply will just run fine, if it features a P4 CPU-power connector or if you have a HDD to CPU-power cable. A 60W ITX power-supply will suffice.

The backpanel is pretty standard, no suprises here.

 

Let's look at the new CPU:

As you can see, two dies of Atom N270s give you one Atom 330. So, Intel did not do something fancy like doing a real dual-core die. Just two dies stitched on the same socket. They did not improve the design at any level, still 32kB L1 instruction cache and 24kB L1 data cache with 512kB L2 cache but this CPU is suppose to be energy efficient, and it does a great job there.

The FPU is still slow and even a dual-core can't match a single-core Celeron 220. The Atom 330 is clocked at 1.60GHz and the total TDP of both cores are 8W, with a typical consumption of about 5W. The downside besides slow execution is the bundled 945GC chipset, which has a TDP of 22W and 3W for the ICH7 sSuthbridge.
