The 4330 is ATI's slowest dedicated graphics part, commanding 80 shaders (stream processors) at a low 450MHz core clock speed-25% slower than its desktop cousin the Radeon HD 4350. Running graphics duty alongside the Core i5 is an ATI Mobility Radeon HD 4330 with 512MB of GDDR3 video memory. It comes with 3MB of 元 cache and a stock clock of 2.4GHz that ramps up to 2.83GHz using Intel's Turbo Boost technology. Packed into our review unit is Intel's latest and greatest in the form of the Core i5-520M CPU, built on a 32nm process with two physical cores and Hyper-Threading adding two more logical cores. Add in the Ice Blue chassis and the current price is $979. The configuration we received for review is the highest priced model with a Core i5 CPU and discrete ATI graphics. With a bit of searching we can get to the appropriate models, and at present the Inspiron 1564 has four available models. Finding the Inspiron 15 with Core i3/i5 on Dell's site is a bit trickier than usual as well-you're more likely to find the older Core 2 based Inspiron 15 models. Unlike previous models, you can't individually select memory, hard disk, processor, and graphics-they're all bundled now. This may simply be for the initial i3/i5 launch, but at present Inspiron 15 options are very limited. In the process of reviewing the Inspiron 15, we came across an unfortunate change of heart from Dell: their notebooks just aren't as configurable as they used to be. HD Audio (2 stereo speakers with mic and headphone jacks) Dell's affordable new Inspiron line seeks to change that, and today we have the Inspiron 1564. Sony's been able to balance powerful internal hardware with light, stylish builds for a while now, but they've largely been the only game in town. Crossing paths with this smart design evolution has been the continually rising popularity of Apple's MacBook line and the slimmer form factors of notebooks based on Intel's CULV platform and AMD's Athlon Neo processors. Gone are the bulky gray-and-white monstrosities in favor of a measure of customizable colors and sleeker, more spartan designs. If you are going to have to get new networking hardware with BT Infinity, there is a very good chance that the replacement router will be wireless N compatible so you should see a fair improvement with either of the three cards over the 1397.Watching the evolution of Dell's 15-inch Inspiron line is interesting, especially when you look at how the chassis designs have changed over the past couple of years. The DW 1505, 15n are wireless N cards so they all will be considered upgrades. After posting my reply I noticed that you did mention that you are replacing the 1397. So when working on a reply I don't always have the thread title showing. If you want the card that has the most options though, the Intel 5100n should be your choice. So as long as you currently have the DW 1505, DW 1515 and the Intel 5100n you should be fine. All three of the remaining cards are both Wireless N and dual band cards, so they can connect to both 2.4 and 5 GHz networks and are 300 mbps cards. Of the networks cards that shipped with your system, only the DW 1397 is not a wireless N card. A.and B networks are the earlier technology with G and finally N networks coming later. I suggested the Intel card simply because it had the widest range of networks and channels in one card.Ī /B /G /N are the types of wireless networks that are available on the 802.11 (WIFI) family of wireless networking. Really before upgrading I suggest testing your existing wireless card and see if it does what you need it to do.
