Another ATI Radeon HD 5450 review, this time from TechSpot:

The new Radeon HD 5450, code-named Cedar Pro, will be the most affordable graphics card belonging to the HD 5000 series. This is also the first on AMD's latest wave of graphics products to do away with GDDR5 memory, replacing it with older GDDR3. Naturally, the Radeon HD 5450 is not designed exclusively for 3D gaming and certain versions will support advanced features such as Eyefinity.

The Radeon HD 5450 is stepping in to replace the Radeon HD 4350 graphics card which currently retails for as little as $35 - $40 (512MB) and $45 - $50 (1GB). AMD expects to ask between $50 - 60 for the new HD 5450, but we believe those prices should settle down a little closer to the levels of the older HD 4350 when old inventory is depleted.

Looking at the current market we have the GeForce GT 220 retailing for $60 (512MB) and $70 (1GB), while the Radeon HD 4650 is priced at $50 (512MB) and $60 (1GB). Both graphics cards are considerably faster than the Radeon HD 5450 in gaming scenarios, but once again we would recommend spending an extra $30 for true gaming-level performance and not the extra $10 for either of these -- (Ed. Note: there's also a missing Radeon HD 5500 coming up pretty soon).

The Radeon HD 4350, which the Radeon HD 5450 seems to replace is priced at just $35 (512MB) or $45 (1GB), while AMD expects to charge a bit more for the Radeon HD 5450 at launch ($50-60).
