You wanted back ground on the phone huh were here it is. The radar sports the MSM8255 with the Adrdeno 205 GPU and the HD7 sports the QSD8250 with Adrdeno 200. Now these numbders seem like they make a difference right? Wrong because the difference between the two CPU is that one may be 45nm were the other is 65nm which in this cast only help to lower the power. As for the GPU nothing changed, well I guess you can count some shader upgrades here and there. O yea and before I forget Qualcomm didn't change the chip set until the role out of MSM8655 and the MSM8255T. They wouldn't have change it then if it wasn't for Tegra chips taking all the spot light at the time. So there is your background theartiszan and have a nice day, LOL.
Good start to your research khan.
Too bad its wrong. And it is not I who is ill informed sir.
While yes the biggest difference with the 8255 was 45nm process it did result in making less heat and consuming less power. It did also see a boost in actual process times due to the newer design and second generation unit and instruction sets.
Also the adreno 205 can be 3 to 4 times faster for graphics.
Even tests done on android between the nexus one which is same 8250 to the g2 msm7230 adreno 205, which is only 800mhz second generation too, prove that. And that second gen unit at 800 mhz out performed the the older 1000 ghz unit in both cpu and gpu performance.
And that is also not mentioning that the new 8255 has dual channel memory where the order 8250 didn't.
So while yes it does have a smaller screen, same camera, and less memory since was trying to be made cheaper and utilize cloud, it is still upgraded as far as performance goes. And the smaller screen does make it easier for most people to use over the larger bulky hd7 or hd2.
That was where there was really no upgrade going from hd2 to hd7. Only changes beyond the OS was a small bump in ram and a new external look.
There are always a back and forth between which carriers have the better phone. Shortly tmo is gonna get the htc one s which will be the best android phone out state side for a while first. Just at a low now for wp7 and there are less of those being made over android as a total. If you don't like current offerings just wait and something better will come later. It always does.
And by the way I didn't work for T-Mobile or sell their product. I do however work in computer science field and happen to know a thing or two about technology.
And don't take only my word for it.
Here is a review and picture of the two devices with the results in both showing the difference.
And the writers comments, again not my own or T-Mobiles, show that the radars performance is better.
Boy, if I had known that writing this little complaint would generate this much controversy, I might not have gotten it started.
First of all, I did get a Radar. I needed to get my stepson a line, so I got the Radar and gave him my HD7. I figured that I could always swap back if I didn't like the Radar. What I consider better about the Radar are:
- Graphics are faster, but only marginally.
- 4G is MUCH better than 3G
- I can stream music and video.
- I use the connection sharing feature a lot, which is the main reason for getting the phone.
- Battery life is MUCH better.
- I use Tango (the video chat application, not the OS), and having the two cameras is a plus.
What I don't like:
- 8 gig of space is pretty ridiculous.
- I can't really keep any podcasts or music offline on the device.
- The camera is nice, but since you can't stream video to SkyDrive or Facebook, the lack of storage takes away from its functionality.
- Sound is MUCH better on the HD7. I'm talking about from the built in speakers, not from the earbuds.
I'm still using the Radar, but I really wouldn't consider it an upgrade. The HD7 was/is much better when used as a media device, but the Radar offers the utility of a faster data connection and connection sharing to my laptop and Kindle Fire. The connection sharing ultimately won out. If you use your phone for music or video, you should stick with the HD7.
Whether the Radar is an upgrade over the HD7 wasn't the question I originally posed in this post, I think they are pretty equivalent devices. However, the Radar and Lumina 710 are the bottom of quality for the other Mango devices on the market, which they admit. It would be nice if TMobile carried a high end WP7 device.
Everyone seems to have been consumed by this debate about whether the Radar is an upgrade or not, but I did try to address your original issue about why TM don't carry a high-end WP7 device in my post from a couple of days ago. You might not agree, but I do think that it is a pure matter of economics and the TM customer demographic.
Since TM have to persuade (ie. pay) the manufacturers to build a special configuration on every device to support their enforced dependence on AWS bands for 3G/HSPA+, the ceiling on potential sales will be a very important consideration. Right now, a high-end WP7 device would only move a few thousand units per month, based on the market presence of Windows phones in general. That isn't going to cut it when the top shelf devices are customarily moving tens of thousands.
I think it's as simple as that, not some blinkered outlook or foolishness on the part of the TM management team.
