What was the growth rate for the consumer side in 2019
n a little bit 5G performance is actually going to be, especially on the mobile side, going to start ramping and we believe that will be definitely boost up some of the areas -- in this area. On top of that, there is also the routers and switch related to the 5G. So we think this is going to be a bright spot for us.
For the computing as well, right, if you really think about and we talk about the data rate, we talk about the speed. So we believe the computing, especially high-end server and router and storage will continue to drive some of the upside momentum and opportunity for us, right?
I think for consumer side, right, the IoTs, even related to 5G, that's actually going to drive some of the new demand in this area. So we pretty confident we continue to focus on the areas we've been talking about, right, 5Gs within communication, high-end server, storage within the computing area and IoT on the consumer side on top of the industrial automotive that we showed significant performance in both of those areas already, right. So that's -- we will continue to focus and that's not going to change in 2020.
Tianyan Goellner -- Sidoti -- Analyst
Okay. But in 2019, I think all those three end markets were down like single digits or low-single digits. So should we expect the trend would be very similar in 2020?
Emily Yang -- Vice President, Worldwide Sales and Marketing
When you say single-digit, you mean the growth in single-digit?
Tianyan Goellner -- Sidoti -- Analyst
Yeah, correct. Yeah, correct.
Emily Yang -- Vice President, Worldwide Sales and Marketing
Right. But if you can see the overall market in Brett's comment, the overall market with our participated area 6.6% drop, right. So even with the single-digit growth, from Diodes, that still outperform compared to all our other peers in the industry, right.
Keh-Shew Lu -- Director, President and Chief Executive Officer
If you look at minus 6.6%, plus 2.9%, then actually it's almost 10%.
Emily Yang -- Vice President, Worldwide Sales and Marketing
Right. Right.
Keh-Shew Lu -- Director, President and Chief Executive Officer
Okay, so.
Emily Yang -- Vice President, Worldwide Sales and Marketing
And then also, for example, in the computing area we are all aware off the Intel chipset shortage and stuff like that. We believe in 2020, the situation will improve based on Intel's announcement. So that's the other area that -- it's also driven by the market and also driven by the other vendors that are driving the market, as well.
Tianyan Goellner -- Sidoti -- Analyst
Okay. That's very good. So my last question, if I may, would be for Brett, on the capex. You just mentioned that in the prepared remarks, that 5% to 9% of revenue would be the good assumption. So I'm wondering, considering in the third quarter and fourth quarter, that capital intensity was at like 7.9%. Should we assume at higher end of 5% to 9% or just the midpoint?
Keh-Shew Lu -- Director, President and Chief Executive Officer
Well, let me answer this because I will not allow, OK, the capex above our model, because our model is 5% to 9%. So I will not allow it. But only one case, if we alter the space in Chengdu then we will build at Chengdu another big building, another facility and the equipment and all. So when we -- out of the capacity of space for Chengdu, we do need to build the building, then that will be boost up our capex a little bit more. But fortunately, they are not depreciated in five years. They are depreciated in 15 -- it's 15 years. So it's not a big depreciation. Okay. So we will still try to keep it -- we will still keep it at 5% to 9% model.
Tianyan Goellner -- Sidoti -- Analyst
Okay. Thank you. So that's all from -- for me.
