I think as it stands, this question is too broad.  There are **many** studies comparing climate models, either with each other or observations.  Many of those studies focus on particular topics.  For an overview, start with the IPCC AR5 WG1 report.

Agreed, the answer to this is "yes".

Are there any studies comparing different climate models on how well they've forecasted the climate in the past?

Yes. The biggest and broadest are the **Palaeoclimate Modelling Intercomparison Projects (PMIP)**, which are the past-climate equivalent of the Climate Model Intercomparison Projects (CMIP).

The latest is [PMIP3](https://pmip3.lsce.ipsl.fr/). It includes [many of the same models](https://wiki.lsce.ipsl.fr/pmip3/doku.php/pmip3%3adatabase%3astatus) that were used in CMIP5, as well as other models that are more focussed on representing past climates. The "[overview](https://pmip3.lsce.ipsl.fr/overview/)" link on the PMIP3 page gives an indication of what the project covers, including experiments into the impacts of climate forcings, as well as benchmarking and comparison of models (e.g. quantitative and qualitative assessments of model performance over past climates).
