Interesting specs. I bought two LTs, shortly after they were released. For some reason, they came with different remotes, they are both model "2400D". Which CPU does that come with?

I guess it probably doesnt matter, since I am selling them and buying an XD anyway.

I think the 2400 is the base model number and the letter after that is just to indicate something else.
The 2450 is the newer LT that uses a different processor.

Right .. the marketing department is confused ... Why are you using Roku 2 HD and now Roku HD ? Planning for a Roku -1 HD in future ?
Who is giving all these useless names and confusing numbering ? Why not fix it ..
If LT and HD are the same, and HD cannot play 1080p HD, then why call it HD , i know it has 720p but then looks like the focus of Roku HD was "HD". and it is not fully capable of that, right. Rather call this as XS .. Anyways now that LT and HD are the same .. why not just give LT and not HD , and ah . i am confused , if Roku wants to make people believe there are different models ... it hurts people , because of the confusion.

So simple, give better names and distinguish features properly . Also after Roku 2 HD, you should have Roku 3 HD , you see 3 comes after 2. So if Roku 2 HD is older than Roku HD, then i am just confused. Who is the marketing person ? Who can explain why this confusion ...

I agree. I also thought it was stupid and confusing that Roku HD, does not play 1080p.

If you're getting confused with names, try figuring out products from Nvidia[GeForce] and Apple.
What I look for in a device/gadget are the model number and specs, not just the name of the model.

HD starts with 720p, when you go higher, it's usually called FULL HD.
What is High Definition Television (HDTV)?
The Advanced Television Systems Committee (ATSC) divided HD into three categories listed in two different forms - 'number of lines + type of scan' or 'number of pixels' (vertical by horizontal).

A Breakdown of the HD formats :
- 720p ( 720x1280 - 720 lines, progressive scanned)
- 1080i (1080x1920 - 1,080 lines, interlaced scanned)
- 1080p (1080x1920 - 1,080 lines, progressive scanned)


When the first LT came out it had same specs as the R2 HD, else the GPU[I think]. When the New Roku HD, it used standard composite output ports instead of the 3.5mm jack[?]. Now with the New Roku LT the ports at the back seem similar and the only difference is the processor.

I haven't had any solid answer and I am interested what makes the $10 difference between the new HD compared to the NEW and Previous LT.

Where do you guys see that any model has a GPU?

Some people[including myself] reference the Roku SDK docs here.
I don't think it's a full-on GPU, but it's something like that[or so I think].

You are not referring to the API are you? I think that is software related, not additional hardware.

LT's generally speaking also have less memory for storing channels, and I think, lack hardware-accelerated OpenGL.

I know this is an old thread, but the difference I've noticed with my old LT 2400X and the HD 2500X (which I understand is similar to the new 2450X LT) I had before selling it were as follows:

- Ran incredibly hot while playing, and warm at idle (even after overnight). The 2400X ran completely cool, even while playing content.
- Pausing, skipping, rewinding on Hulu and Plex apps sputtered more often on the 2500X and often froze much more often (I had to reset the 2500X several times during a week while the LT rarely needs resetting). Netflix seemed OK.
- Video playback on Hulu sputtered after watching several shows. Same with Plex. I can stream 1080p content wirelessly to my 2400X without any issue at all, while the 2500X sputtered after several movies
- Issues with wireless "connection test", where it would say it couldn't connect, while my 2400X had no issues at all in the same location
- No temperature indicator (I forgot the code to get to that hidden screen)

I eventually sold the HD and just ordered a LT from roku.com, but didn't realize they changed the model from 2400X => 2450X. I'm assuming the 400mhz MIPS processor is why it choked so much, compared to my LT 2400X and my XS2 3100X downstairs which work perfectly. If I end up receiving my new LT and it's the slower, revised 2450 model, especially if it has the same issues the HD had, I'm returning it and hunting down one with the ARM 600mhz processor.

I looked at pictures of the LT on their website. It seems the mobile version of the site has the older style (i.e., smaller, ARM model) images, while their main site has the newer one (.i.e, larger, MIPS model).

If this is true, I don't understand why Roku would decide to sell a larger, hotter, slower version of something that worked perfectly in previous versions.

Hi marriedgeek,

I recently bought an HD-- it does not run hot nor have I seen the slow sputtering on hulu (I dont have plex) but at this point it seems every bit as responsive as my two LT's-- granted I have only had it for about a month -- did it take a while before yours started acting up?

Thanks for the reply. Are your LT models 2400X?

EDIT: No, it has always been acting up. At first I thought it was the wireless, so I upgraded and optimized that. Turned out it wasn't that. It was past 30 days at the point at which I sold it.

both my LT's are 2400x my HD is a 2500X if this has the arm processor it may explain why I havent seen any issues

So has Roku stopped selling the 2400X models in favor of the 2450 completely now?
